Datum OSP compensation as a datum modifier, need the ability to shift Datum to compensate for coatings.

Need the ability to easily compensate a set value per Datum, if a Datum surface is going to be anodized we need to compensate for the coating thickness, if you add a modifier to do this similar to the Unilateral Tolerance modifier it would save a lot of thought, effort and alignments to compensate for this while needing a separate program for pre and post OSP with these compensations. With this modifier we could just remove the modifier or change the value to compensate.
