I'm hoping to be able to have IR remote capabilities for different lighting themes in my theater area using the Harmony 720 and Lutron dimmer switchs (Spacer)

Can the 720, 6 hard buttons in the colour screen area be reprogrammed from what they presently say to something else? ie. I'd like to reprogram the "watch VCR" button to say "LIGHTS"

Once i press the LIGHT button, i'd like to have come up on the screen my different theme options;

Theme 1 - Games
Theme 2 - Movies
Theme 3 - Intermission
Theme 4 - Office

If the answer is NO, is there another way to do this? Maybe have the remote "learn" the different themes on 4 different buttons.???

There must be people out there that want to do this...but how?

Thank you for your help!
