wishlist: Keep hierarchical sheet pin locations linked for multiple instances (lp:#1825546)

Original report created by Rene Poeschl (poeschlr)

Instantiating a hierarchical sheet multiple times right now is kind of
error prone if one needs to do later changes. (for example adding new pins
might require old ones to move.)

Would be nice if there could be a way to tell kicad that all sheet
instances should be linked such that editing the pin location in one edits
all others.

Yes i am aware that one could copy the full instance around but that is not
really viable after one has already made parts of the layout. (annotation
would change)
