Dominion teamcolor options help needed please

I have a problem that i can’t figure out a solution to. See, I was planning to make a Halo 4 machinima using the Dominion gametype because I love the Dominion items and the way base upgrades. However it seems to me like Dominion is teams only, and that means I would not be able to use custom armor colors. I have looked under settings for a team color diable setting, and have tried other non team gametypes like king of the hill and such. But the closest i can get is having the items on the map, but not be functional. The only solution I can think of now would be if an update added that option, or when file browser comes out for a download gametype like Dominion, but with the settings needed for machinima. If anyone has a solution I could use I would really appreciate it.
