Is it possible to add your created race to the selection screen in custom games?

I made the Naga as a playable race, is it possible to make them selectable for custom game?

Wow, that seems amaziningly difficult and they've tried pretty much everything and not got it working short of the names appearing on the menu....
I really wish they could get it working, I defiently want to add the Legion and Naga to the menu and have em load up with those races starting units and perhaps custom music, but it doesn't seem possible. short of dll editing.
