DA2 mod

Is there any mod that would allow swapping or freely choosing companions in DA2? I'm mainly asking for the dark roads quest in Act 1. I always want to make Carver a >!warden,!<which means my party is always >!Varric, Carver, Anders.!< I would love to take different companions there. I have tried to search for it on Nexusmods, but haven't been able to find anything.

Also, is there a mod like this for DAI "locked in" companions for certain quests?
