How to create a negative shape in a custom pad in KiCad 8

I am trying to make a footprint with a custom pad with this shape. I made the general shape with “Edit Pad as graphic shapes”, but I was not able to add the negative circle (I created the image in paint). I tried adding a circle on different layers, but it seems like only top copper does anything (add, I want subtract). I also tried creating the shape with lines and arcs, but I was not able to fill it.

How can I add a negative shape?

It works for me.

  1. Create a footprint
  2. Place a pad.
  3. Enter Pad Edit Mode with [Ctrl + e].
  4. Draw some lines on the F.Cu layer.
  5. Draw an arc. Together they must form the outline. This is easiest if you draw it on a suitable grid.
    image Also note, that for the Pad Edit Mode to work properly, your graphics must overlap with the pad. Do not draw it just to the edge of the pad.
  6. Draw a box around the lines and the arc to select them.
  7. Right mouse button, and from the context menu: Create from Selection / Create Polygon from Selection. (Use centerlines, delete source objects).

  8. [Ctrl + e] again to exit the Pad Edit Mode.
  9. The polygon is now a part of the pad:
