I often run into situations where I would like to define a board cutout in a component footprint, e.g. a notch in the edge of the board for a connector. So far I've only been marking the hole on a mechanical layer, and then creating a new cutout on the PCB after it's exported from the schematic. This is obviously not ideal since I need to do these each time I use the part, and would prefer to only do it once in the PCB footprint. Is it possible, or is there some other workaround?
