That's my point:

Inside Workshop Scan number always change if you go back to the place, delete some scans, and re-process the Space.

This is a very stupid thing to do, why not using same numbers as the Capture applications ?

It's so frustrating to search every time for Scans that I have to hide, and they never have the same number !
I have to do this on hand !!!

Insanity: doing the same thing over and over again and expecting different results.
