alright, so i am starting to get into arcade map building and i was wondering, is there a way to make a carrier a turret for the last upgrade? I put the things i want in the "Build Structure" and "Build advanced structures" Catigory but there is one last thing. How to i make buildings that don't attack and regular units to be stationary and attack (Like the photon cannon) If you would help me i would be so great full and ill put your names on the loading screen under a "Special thanks to".

Thanks :)
