Audio selection in Android TV

[WoodyBABL]

In the Android phone app, I can make audio and caption track selections before I play. Unless I'm missing something, I don't see the same option in the Android TV app. You can make the selections once the file has started, but that sort of diminishes the cinema experience if you have to pause just as the movie's starting. Am I missing g something? Why would the UI be different between the two Android experiences? 

Thanks.
