Eagle CAD Non-circle through hole pads?

Question

I am trying to make a custom through hole pad for a part but it needs to be either oblong or rectangular but there does not seem to be a way to specify anything but a circle drill hole. I know board houses can make plated through hole square pads but I cannot seem to figure out how to do it with Eagle CAD? I see I can draw tracks on the pad with a circle hole in it and block out part of the hole but I am not sure if that will be understood by the board house with respect to a rectangular plated through hole pad? Any suggestions?

I have oblong pads with oblong milling. On the top (and bottom) layer the oblong pad is present, but the inner pads seem to be just round pads, not oblong pads. And from the image you can see the milling layer goes outside the round pad and theoretically a trace could end up being milled on the inner layers. I talked with Eagle CAD support again on this and they said it is a shortcoming of Eagle CAD and they are in the works on a fix or enhancement. In the image you can see the thin blue oblong shape, that is the milling layer. The red is the p layer and the blue is the first inner layer. You can see the pad on the inner layer is not the same as the pad on the top (or bottom) layer. Hi Chris, I emailed you privately on this, but I think its good to have it on the forum as well. Check the make-long-pad-inner-layer.ulp that comes with EAGLE. It basically makes sure the pad shape goes on all of the inner layers. In any case it an area for improvement in EAGLE.
