Alter contact conversation priorities

[srmalloy]

I don't know if the code is set up to allow this, but it would be useful if, when you went to a contact with a full roster of missions and couldn't take any more, but you'd outleveled the contact, the contact would give you the "you've already solved all my problems" dialog rather than the "you need to take care of some of what you're already doing" dialog, which forces you to go out, complete a mission but not take a new one, then go back to the contact that wouldn't talk to you, only to find out that they have nothing for you. Given how easy it is to outlevel contacts (even if you've never talked to them), or to pick up a full slate of pending missions, having them concede they've got nothing for you up front would be a timesaver.
