I am using several MX-780s with a MRX-350 base.

I have multiple TiVo units in a system so when using any of the TiVo devices I have the IR Output set to a specific Port (rather than ALL). Yet, while using the TiVo in the kitchen (local TV), I want to program a 2nd page of soft buttons to manage the volume of the Main Receiver from the Family Room. Unfortunately, since the TiVo is using Port #2 and the Receiver is connected to the MRX-350 on Port #1, I can't figure out how to do this.

Is there any way when programming a button to dynamically switch the IR Output port so it can be different than the default for the Device?

Thanks, Jeff
