Before I Ask...

Before I post this to product suggestions, I want to make sure I just didn't overlook this functionality.
What I want to do is be able to set the perspective to match any camera in the scene I pick. So, if I want to make changes, I don't want to use/move a camera. I want to match the perspective camera to the static camera so I can then tinker with the scene.
Sort of like a "fit to" for cameras.

If I understand you correctly, then yes, this is easily possible. What you want is to load a new camera and match it to the perspective view, right?
So, when you load a new camera, a window appears, in which you can give the cam a name. There you also have a "more options" button. Click it and the window will show more options. You will see three possibilities where to place the cam, The second one is to match the cam to perspective view. I am not at my home PC at the moment, so I cannot make a screenshot, sorry. But try it and you will find it easy to do.
Hope that helps.
He's after the inverse of that ... and in DS, no, I do not think it is possible. What I do is run with (at least) 2 cameras in play, one named 'SceneCam' which I'll use for the final render, etc. Once I have that setup just as I want I'll seelct it in scene tab and then in properties lock it so I can't change it's position by mistake. I'll zoom round the scene tweaking things with either another camera or the perspective view. To make alterations at wildly opposite locations I'll either use 2 'posing' cameras (usually I'll 'fail' and move/use the wrong one by mistake!) or use Ctrl-F (to frame) an object I know is close to where I want to be looking.
Of course, if this isn't in DS all bets are off ;)
A similar topic popped up a while ago and I still can't understand the want for this.
In my mind, if you want to see what the camera is seeing, then simply select it from the views and voila, you are seeing what the camera sees. Then when you need to move around and look at the scene from different angles, switch back to perspective view.
If there are angles that you tend to go back to a lot while working on a scene, then add another camera there for a quick "jump to"
Another idea:
You are watching through a cam and want to move from this position, because switching back to perspective view jumps to a completely different place in the scene. But you do not want to move that cam. Right?
Ok, view through your cam. Create a second cam on exactly the same position and angle (more options in "Create Cam"), switch to that new cam and move from there. Good?
Click on the camera and then click on the box with the + in it which focuses the perspective view on that camera then move the view to line up with the camera view.
In the scene tab, click the camera with the position you want so it highlights, then control-C. Then click to one you want to move to highlight it, then control-V.

There's a link to a lighting tutorial in my siggie and the artist there explains very nicely how to use each of the viewing windows to advantage like that.
Thanks @patience55 for the link.
Ooh, a chance to tout the benefits of Puppeteer (which no one ever uses)! ;) This won't work with a perspective camera, but it's a method to save a lot of normal camera positions for easy experimentation and jumping between them.
- Make sure your camera is selected in the Scene panel.
- Open the Puppeteer panel, make sure the Edit button is checked, and click anyone on the grid to create a dot. This dot saves all of the parameters for whatever item is selected, in this case, your camera. You can now adjust your camera and always be able to go back to the saved position by clicking on the dot. Save lots of dots as your work and delete ones (right click on one for options) that you no longer need.
- This essentially works like the Pose/Camera dot feature in Poser except you get an unlimited amount here and things can be animated between the dots (that's the original purpose of this plugin anyway). I use it all the time for poses and cameras when creating images, as it's easy to update them and delete old ones without having to constantly save presets to your content directory.
Hope it can be of some help. :)
Greetings,
The points about moving a second camera around are great, but they miss one of the major points of using the perspective camera in the first place.
It doesn't show up in Undo history.
If you use a 'real' camera for all your swinging around, so you can do precise movements, etc., then it pollutes (and eventually truncates) the undo history.
I too would love a way to say, 'Now, sync my Perspective view up with THAT camera' button...action...script...thingie.
It's probably programmable, but my dzscript-fu is weak.

Thank you @SnowSultan. I haven't learned about Puppeteer yet. I think I will look into it. Thanks for your suggestion.
