can import just morphs and apply them to a previously imported model?
if I get new morphs or geografts in daz i want to apply to a genesis model I previously imported into blender is it possible to do that with differmorphic, like say I have a bunch of new favorite morphs i didnt have before that I wanted to bring in for the previously imported genesis 9 model already in blender?

For this kind of things it is advised to always keep a "daz rig" version of the figure, before converting to rigify or mhx. On the "daz rig" version don't merge geografts either. If you do that then yes you can import extra morphs on the figure or the geograft, using "import custom morphs".

p.s. Or of course you can always import extra morphs the blender way, that's exporting the shape as obj then merging as new shapekey.
shape keys > menu > join as shapes
