It would be cool if someone borrowed from the Factorio interface and let you paste in blueprints. I'm not an experienced enough PCB designer to know how terrible of an idea this is, but it sounds mildly feasible.
You can do this, though the interface tends to be clunky. It can he valuable but mostly for between different designs done in-house, no-one is trying to make easily reusable building blocks at this level (unlike footprints, where people are at least trying, but not generally succeeding)
