Threatlevel0

Just started doing random AE missions with a couple friends and there are more than few farming ones that set you to level 1 and have just bosses. My friend was trying to make one with just custom bosses he made, a single boss in each group, and I tried to helped and we cannot figure it out. I've googled and tried to find guides to AE mission creating but no luck. So maybe a simple, dumb question or not, I don't know, anyone have an easy answer to this? Or a link that might?
