Stop creep from spreading

[BaconMcPig]

I was wondering if there is a way to make using an editor, not a mod, for sunkens to not generate any creep? I've been trying out various unit properties but none of em are what I'm looking for.

only way to do it is to have the zerg buildings on terrain that you cant normally build on

Aww that's not going to work for my purposes, I guess I'm going to have to go with bunkers instead.
