Military Academy

Okay, I know this info has probably been posted somewhere already, but I have just spent a very frustrating hour using the crappy new search engine and I can't find it.

Can anybody tell me how to mod the game so that I can build more than one Military Academy?

No need to mod. Build a cathedral/grand mosque ... build a military acadamy, destroy the cathedral/grand mosque, build a new one in another province, build a MA there, destroy the cathedral/grand mosque.

I can't help with modding though.
