i wrote a program a few years ago that generated morph targets for each point in an exported body part.  it was my only program ever!  probably pretty easy for anyone with experience in programming. the trouble i had was loading the set i would use in a morph.  one vert was never enough so i grouped them by lines and used loader script.  this was poser 5 and the program would bog down.  so the brush came out and i abandoned the thing.

 

if you need to see vertex numbers you can install bender, and there is a script called view3d which places vert numbers over each vert selected in the view.

i'm with you though a python script to generate the morphs needed on the fly would absolutely kill.

go that way really fast.
