Hello, I just bought a RM-AV3100. Is there a way to step through a macro with a key press. I am wanting to program a "News" button that will act like a favorite channel button but just for news. So when I push it the first time it changes the TV to ABC, second time changes the TV to NBC, third time to CBS, etc. I would like to have several of these buttons for stuff like sports, movie channels, etc.
