Allowing landscape mode for a specific controller

I'm currently using Conductor in an app that is mostly
single-activity-multi-controllers (great library BTW!).
The aformentioned activity is defined as 'portrait' only in the app's manifest.
I would like to allow landscape mode for a specific screen.
One way to implement it would be to use a separate activity for that screen but
assuming that I would like to use a controller instead,
what would be the recommended implementation?

I tried to implement it simply by using the Controller's 'onChangeStarted'(swapped-in) and 'onChangeEnded'(swapped-out) methods to invoke the getActivity().setRequestedOrientation(..)
and it basically did the trick(tried to apply it to the demo app).
