Changing Audio Level via a programming command

[sjj31a]

Here is what I am being challenged by, I have 1.6 and love the new zone setup. I have all my zones defaulted to levels that work great when I am running the entire house. However, I like to Jam in the morning in the shower and have setup 6 custom buttons on my 10.5" keypad for various selections. When I press the button I get the low default level (i.e 45%) and want it automatically to move to 85% when I hit the quick key. I tried sending volume up pulses but that did not work. Is there a way to keep the default at 45% but programatically change to 85% when the quick key is hit?

Thanks so much!
