Question about Dominion Objects in Forge

So I’m trying to set up a map on Halo 4 (360) that is a team slayer oriented map, however I would like to know, cna I make dominion bases that are usable in slayer or do I have to stick to dominion? I seem to recall being able to activate dominion bases in slayer…

I don’t remember if you can create it or not, as i’m not sure, watch some videos about how to do it and if you can or not
