You're going to kick yourself when you hear this. You are right, it is under player data! You just go to the enemy player, follow it to the right all the way, and click "AI." Then click "aomdefaultai" from the list, because the other ones probably won't work with most scenarios. Simply click AI. Then it will do all the stuff from a random map.
I do that and it doesnt work, so I stick to reviewing other peoples maps rather than makle my own lol
