Yes sure, but it's a bit of a whack-a-mole right:

Nothing: Opus plops down everything into one big schematic sheet

"Use hierarchical sheets!": Opus uses them but does not realize they can be multi-instanced

"...":

It would probably be well worth to optimize this on synthetic projects, but realistically we are small shop, our required PCB-design output is not that masive, and I expect Opus 5.8 to just do the correct thing automatically as its being RLHFed on these tasks as we speak :)

It's probably a case of you can't write down infinity. There is probably no general prompt that works. Even many humans can't be given a general conceptual instructions.
