Denon 3313CI Zone 2 source input

The new Denon 3313CI enables Zone 2 to watch different sources than the Main Zone. Are there any IP commands that can select Zone 2 inputs?

I was reviewing Denon’s protocol document and it looks like it is possible, but I am not sure how to enter custom IP commands for the device.

I figured out Zone 2, by adding a second device for zone 2.
