I think what you are missing is that there really isn't a square pad on the plane for which you need to generate a clearance. You are generating a blowout around the hole. Plane clearances are normally expressed as a void expansion around the hole.
If you mean that you have described a square hole for the fab to route, then the easiest way to clear the hole on the plane is to simply place a square pad on each of the plane layers (i.e. a single layer pad on each layer) that is the desired clearance around the square hole. Remember, what you see on the planes represents void - what you don't see is all copper (they are negative images).
