Check out the Daz store for the Mkscripts package. I think it might do the copy prop. The magnets thing is definitely doable. Post the request over on the Python Scripting Forum wishlist. If no else gets to it I might see what I can do. Would you want the magnets made symmetrical or the resulting morph? I have a script that I've been using for making symmetrical morphs for characters that have perfect right/left symmetry ( ie the right arm mesh is a perfect mirror of the left arm). I was looking at extending it some to handle "near symmetrical" characters where the one side has been displaced slightly from the other during the character generation.
