I have been fighting with this issue with my Harmony 880. Based on Harmony restrictions, I am thinking about setting each light to a different letter, with the same number (i.e Kitchen A3, Den B3, Livingroom C3), and then I can change the labels on the Harmony such that House Code A is Kitchen and House Code B is Den. I will then have to know to press "3" & "On" to turn on any of the devices. This sounds like a pain, but I can't think of any better ways. Note that I do not want to use macros, as I want all the lights to be in the same Device.

My question - does anyone know a better way (i.e. am I making this too complicated)?
