I see the whole thing like this:
Stickers are separate components for me.
We could list the set in the header of the sticker where the sticker was first used (as with the printed parts).
Shortcuts from straight stickers are also superfluous for me.
I'm not strictly against shortcuts when it comes to shaped stickers, but in my opinion they don't have to be.
While I was writing these lines, Steffen replied, (#21) and I also like this approach.
I just tore something back and forth.

If nothing goes right, go left.
