Mixed orientation support

I have a video app where the orientation for all main scenes should be in portrait mode.

However I’d like to support landscape in the scene where I display the video.

As it is now, I can’t allow landscape in build.settings without it affecting the whole app. 

It would be nice if it were possible to have something like a true/false return-value from the onOrientationChange handler that would either allow/ignore the event.
