Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Beta Tired of Arguing with Myself

So after about my 3rd time playing the game (after patch changes etc). I am curious if, as someone playing solo atm, I can set one of the two main characters to choose it's own dialogue.
As of right now whenever the two player dialogue starts I have to choose the dialogue for each of the main characters. In many cases I now have to argue with myself. It's not very fun (I always win) and I feel like it takes the immersion out of the game.
