It does not look like there is currently a way of doing this. I will file a suggestion for this though, as it would make things much easier!
I'm not sure I fully understand your second question. Are you talking about moving the 'Chassis' section under a controller to a new controller in your project? It doesn't seem like the Chassis has many configuration settings at all. I might not be fully understanding this question though.
