I got slightly wrong and would only add the circle connecting the copper circles really is a cut out or negative circle as you call it.

I assume the following objects are equal and give the same result: drilled hole, negative object, cut out.

To drill a hole thru only some of the layers I consider a little bit more involved. If I got objects wrong is less important. Do you think it would be good with possibility to draw on any layer inside element, pin, via, pad for those special cases that are a little bit different?
