Adding AI to games

Playing a hotseat game with my friends, standard settings except for Tb 4/hr jumps.

I’d like to add AI to the other spots for flavor. Can I do this?

I believe if you’re a premium player and creating your own game, to achieve this you simply specify the number of starting positions, wait for your friends to join, then force start the game from the admin menu and the other positions will populate with AI.
