Can it be looked into for the Yamaha R-N303 that on the original remote, it has dedicated buttons for the following inputs: Optical, Coaxial, CD, Line 1, Line 2, Phono, Tuner, Net, Bluetooth. It should also be noted that when pressing any of these buttons, they only perform one action EXCEPT for 'Net'. You can toggle the 'Net' button to cycle through various options {Napster, Sirius XM, Spotify, Pandora, Todal, Deezer, Server, Net Radio, MC Link, Airplay}
Currently, the only thing in the DB for it is an 'Input' button which seemingly only changes the input to 'Tuner'
