Yes, that's doable.
It cannot be inside config though, because (for some unknown reason) the person who made that has it so the configuration stuff doesn't load until world/New(). Whereas this revision stuff is done before any of the map is even instanced.

Would it be ok if I made it a define rather than another obscure external file, I can put it with the defines for server name/whatever. (I tidied all that up recently)
