More than one faction in official Arma Zeus server (16+2))

[Susp1cious 0]

I am currently playing on arma 3 's official 16+2 zeus server, and Im struggling to add more than one faction. When choosing mission as admin I only have the option to make: master stratis/altis NATO/CSAT/AAF but not two at once. I would like players to compete. How can I change that?

There's a ZGM with all three factions inlcuded. It's the one for 64+2 players if I remember correctly.
