Question about Pathing Maps for Doodads

I was wondering if there was an easy way to scale the pathing map for doodads, like when you make a doodad(such as an arch) really big, it keeps its old, small pathing map. There are a bunch of ways around this for cinimatics, but, I'm thinking of maybe using stuff like this in a playable map, and I can't find a place for Scaling the Pathing map. Anyone know anything that might help?

Terrain forum?

Oh, that was really helpful... o_O
There isn't a "doodad" forum, and pathing has to do with terrain, what do you have to do to get help around here?(retorical question)


Edit- okay, sorry, somehow I thought I did post in the terrain forum, but unless a mod moves this over there, what can I do about it? It is still not a terrain specific question, and any help would be apriciated.
