I want to be able to select what device to play from in my smart tv app!

Im NOT talking about playback on two devices here.

I know this might seem counter intuitive, but your visual features are so good that even though I have a separate unit for playing music through my main speaker setup, I would like to have the app on the tv act just as the app in my computer would during playback on a different device.

So I could see what's playing and navigate my music on the TV but play it back on my little Spotify connect box. 
I can already achieve this by opening the app while playback is already happening on my other device, but I just want to be able to do it through the tv app.
