Adding Notes to a Padstack

I'm trying to find out how to add a note to a Padstack so it is displayed in the Notes column of the Drill Table in the Manufacturing Drawing. We are using Cadence Allegro 16.6

I have a Via which needs to be Filled and Capped and need to distinguish these from the other vias on the board, the Drill Table has a Notes Column but I can't see where the information for this column comes from

Any advice appreciated

Thanks
