Trait Zones in Forge

In Halo 4, to edit Trait Zones you had to do so through the pause menu. Since this game’s pause menu is cross-platform, as far as I know, there is no way to edit Trait Zones in Forge. This is upsetting, as they were even reintroduced into Halo 2: Anniversary’s Forge as well. I’ve looked everywhere, and I don’t think I’m able to edit Trait Zones. Are they useless or did I just not look in the right place?

Overall, this just seems like a minor but fine example of how rehashing just looks lazy and thoughtlessly rushed.
