Hey there! I made a footprint for a reverse mount LED where the led shines through the PCB board to the other side.  For the light to pass through the board it should have no solder mask or copper under the component.  In the footprint I put in a soldermask but I don't know the best way to make a copper keepout as well.  The reson I'd need this is if I do a copper pour for a groundplane it'll fill that area and I need it to keep clear. Right now the workaround I figured out is: -put a copper layer in the footprint editor where I -don't- want copper in the final PCB -do the design as normal and place a copper pour on the PCB -go back to the footprint editor and delete that copper area -update the footprints on the PCB  which will remove the copper from the area and leave the ground plane pour in tact. This feels really hacky but I'm not sure if theres a batter way around this. Any one else got a better way to do this?  I'd assume this would also be needed for fiducal makrings and the like.
