My schematics are labelled with X-M-NN notation where X is component
type . M is schematic sheet number, then NN is component number. you can
extend it easily to X-M-NNN if required. And again, I just use
"autorenumber" in gschem. Totally trivial.

But then I use professional fab house who do photo etching, cnc milling
etc etc etc ... ;D and CNC part placement, reflow ovens, wave soldering etc.
