I think it would be very useful for border routing depth to automatically adjust to match the composition thickness. When moving parts between compositions of different thickness in the nest composite I have not found a good way to make this correction when moving to a thicker material. Since the software already adjusts the depth of border routing when moving a part from a thicker material to I thinner one I imagine it would not be to arduous of a task to make the opposite work.
There are no workarounds I have found to accomplish this while preserving edgebanding codes.
