I am using Expedition Ascent/Pinnacle and I would like to selectively add soldermask to a layout design. I recognize that I can edit the padstack and make this happen for specific pads if I need to. Instead, I would like to see if there is a way to add soldermask and only cover a few pads on the board. I know that I can add a draw_object to selectly open soldermask on a layout design. In this case, I would like to do the opposite.
