I want to add a function for the Denon AVR-985; I want a button (LCD button) to increase the center channel volume and another to decrease the volume.

When I go into learn commands menu, it lists these 2 commands but does not state that they are in the database (does that mean that the ones that are listed as in the database will automatically work?). I have the IR code from the Denon website (101011 for level up and 011011 for volume down). Where (which menu and how do I get there) can I enter these codes so that my Harmony One will be able to perform them?

This is important as I do not have the remote to learn the command.
