There are a couple of other requests for Microsoft/Asobo to provide an interface to the camera system. This would make possible what you are asking for and a whole lot more.
It would bring an amazing amount of functionality. For instance, many have been asking for a “Fly By” camera mode. If the Devs provide the API as requested, it would allow 3rd part developers to offer that and other awesome features.
And, they are chomping’ at the bit to get started. We would see solutions very quickly.
I believe this work (creating and documenting the API) would be done by the SDK team.
