Custom pathing maps?

I've encountered a problem with Waygates. Its pathing map is kinda huge so you cannot place other objects near it. Obviously, this prevents me from doing what I want. I tried to remove the pathing map, but that caused war3 to crash. I tried changing it to a farm's pathing map, but then units can't enter it (waygate pathing doesn't block, which the others do).

So I thought, is it possible to make your own pathing maps? How? I'd like a waygate pathing, about the size of a farm's.

Never mind this post. Solved it using a bug ^^.
