Guys, another CCP question.
I see hundreds of Denon options in CCP for different models/zones/etc.
Most are the same code-sets for obvious reasons. Some are not.

Here is my question:
How do I combine:
AVR-3313CI [MAIN], AVR-3313CI [HD=RADIO] and AVR-3312 [IPOD] ?

Selecting one and clicking SAVE imports xx number of functions. 
Selecting second one and saving imports xx numbers of functions, but it deletes first set, and so on.
Do you guys just create multiple phantom devices on hidden pages, and use them that way?
