This is just a feature suggestion/ request:
I think it may be helpful the have the ability to select Sub-DS faces by their surface packing color. If attempted to do this using sub-object selection filtering plus Select by color, but this method does not seem to recognize the surface packing color.
As a side note, I’ve been havening difficulty converting subdiv objects to NURBS with surface packing enabled over a certain face count limit. The results don’t match the set surface packing by color scheme and there appear to be errors with self intersecting loops. I can move this subject to a separate thread if needed.
