"Or is it that you want Poser to be able to analyze the morphs in the figure and add and dial them automatically to the clothing?  (Like Morph Follower in DS3A?)"

Yeah, I think Poser should be doing this automatically.  Studio has been doing this for longer than DS3A.  So does Carrara.  Whenever a piece of clothing is conformed in those programs its automatically adjusted.  There can be some slight tweaking due to poke through, but not nearly the amount that's needed in Poser.  It's annoying to be buying scripts for something that should be a part of the program.
