If I'm not misunderstanding your request, we already have that option. As I understand it, the channels are configurable - so you should be able to have either Range or Room, or both, or neither, as you prefer.
You just click on the arrow of one of the four radio channels and select the channel you want from the dropdown selection list.

Or are you asking for this to happen automatically when you go to the Hangar or O'Club? That might be cool - if you have one of the channels configured for Range or Room - it will automatically be set to "Room" when in the Hangar or O'Club, and automatically revert to "Range" when you leave?
