Enable Buffs and Dialogue for Companions being controlled by other co-op players

[Flipsticker]

When playing multiplayer co op, we're able to increase our party size to bring more people along and let friends control them, but it's currently impossible to talk to companions that are being controlled by other PCs or get buffs like Guidance in dialogue, even though we're all in the same party.

I see this brought up many places, but I didn't know if anyone has made a patch to address this.  Seems like a great addition, if it's possible.
