Hi - very new but learning fast...

What is the best practice/workflow for re-importing a character from CC3 into UE4?  For example, I have a CC3 character which I imported into UE4 and then used the auto-setup plugin. If I want to make changes in CC3 - hair, clothes, whatever - and import those changes into UE4, what is the best way to go about it?  Should I just import as a new asset into UE4 and run the auto-setup again, or is there a better way to update the existing character already in UE4?  Dumb question?  Maybe, I've been known to over-think things.  But thought I'd ask more experienced users for insight on what works best for them.

Thanks!
