Just a use case note: Although I am far from asic projects I would would
have loved to have such a feature in the quiver. The project required eleven
identical subcircuits. They had to be connected differently, though. So,
a simple copy-paste would not do. I addition, I don't like projects with
deliberately broken netlists.
There is a similar technique in vector graphics apps like inkscape,
coreldraw and illustrator. They call it cloning.

Sometimes, this is actually a useful feature. No need to cycle over all
instances if some via needs to be enlarged.
