Unable to select Bluetooth as a source

This app just like the actual physical remote control does not contain all the sources that are avail be on the receiver. I have the avr 1710 model and both the remote and the app have no options to select the Bluetooth source. So when I want to listen to my music on the iPhone I have to physically walk up to the receiver find the Bluetooth source and then I can play my music. At that point I dont even need this app.

Basically app designers can u add the Bluetooth source option please.
