Is there a way to open 2 content library tabs?

So I'm trying to organize my content library using categories... and it is going very slow as I'm having to move each unassigned category group one at a time, then scroll back to where I was... so far I've been at this for hours, and It's getting old... I can drag and drop easily enough if the items are close enough together, but it would be nice to move several items at the same time, and/ or have 2 locations open so I can move multiple files to a section... I found a very old tutorial about how to do this in Daz 2.3, but Is it possible to do in 4.8?
