P20: a "manual" zone?

I have a CD player plugged into P20 and the player does not have a standby mode. So when I bring P20 out of standby the player switches on. But if I don’t intend to use the player during a listening session, this is a bit of a waste. I would prefer to use P20 to switch the player on and off manually.

Is there a way to program a zone for fully manual operation?
