It would be great if there was an ability to add an ID to the surface names, similar to how building materials can have an ID.
It would be used in scenarios like auto-text labels, keys/legends etc.
An example would be:
P1 = paint red
P2 = paint blue
P3 = paint yellow
etc
An auto-text label could then be used on plans to annotate the wall linings, finish etc.
Eg: L1 / P2 / F1
