It would be nice if Prompt Value override prompts were locked in the subassembly, that way when a drafter wants to change a value it doesnt just reset.  Or it notifies them its locked.  Like for Doors or Boxes, you can get to a box or door many ways with Component Inserts or just as an S level.

Some scenarios its prompt is locked, but others it wouldn't be so we cant just "force lock it always".  Maybe the prompt color could be a red field instead of white, anything some sort of identifier for the drafter.
