The semi automated order entry fab I use Does such slots or rectangles with the board outline layer.
If you have a rectangular hole, it will have a min radius on the corners.   If you have a sharp squarish
thing to put in there, overshoot the corner a little with a round (cutter-shaped) cutout, (and some daylight will peek out as well 
as your display).
