Hello, I was wondering if it is possible to switch HDMI inputs when pressing the A/B/C buttons. For example, I have an A/V receiver that has 2 HDMI inputs. When I press button A, I would like the receiver to switch to input 1, and button B to switch to input 2. This way I could automatically switch to the input source, and start controlling it rather than having to select input 2, then press B to control the second device. Is it possible to do this?
