I have a material with special measurements.

Is there any way I can show the  material with the measure I need, insted of the size with cutting edge.

Example:

I know my material is 612mm wide (with cutting). I would like it to be called 600mm.
If I then want to change the measure from 600mm to 500mm. Then I know that it still has my additional measurement of 12mm.
So the visible I see is 500mm but it is actually called 412mm


I have previously used "ddedit" (Editannotation), to write what I want it to be called, but if I later change it, is still called what I have called it in "ddedit". So it doesn't work for me this way

I hope you understand what I mean ☺️
