Skill: Multipart shape ?

hi,

I have a small question, in skill, again !

do you think possible to create a kind of multipart shape ?

For example, i would like to create a multipart shape which:
-add automatically implant, diff, contacts and metal (like a multipart
path)

-can be "stretchable" (i don't know if this term is correct,
gomennasai) in X and Y

-and after a strech, it will automatically re-calculate the number of
contacts to fit the new size.


so ... am i dreaming or is it possible ? If possible, may someone give
me the main idea on how to ?

Thanks and regards,

b.
