I like to turn the volume down on my a/v receiver before turning it off. However, the off button on the Harmony One just turns it straight off. Does anyone know if it is possible to change the functionality of this button to add an extra command?

Obviously, I could create a new activity for powering off but would prefer not to. Also, if I did that I'm not sure how to set it only to turn off the devices which are active - if I tell it to turn everything off it will end up turning on the devices I haven't been using.

All thoughts appreciated...
