Do I understand you correctly that you just want to give one (or more in case of wedges) surfaces that need bumps.
Now if there is a pattern, it is then the task of the renderer to look for the right triangles and quads that are on that surface to apply the bumps to them.
Wouldn't it be easier if the renderer can rely on the part syntax that all surfaces that require bumps to be in the "SLOPE" bracket?
