I have the Hamony 880 and onkyo receiver. One button I use a lot on the receiver remote is the "Surround Mode". When I want that button on the harmony, I have to scroll through several pages till I get to it. Is there any way to move it onto the first page?

The closest I can get is changing the assignment of one of the hard buttons (i used the '+' button) to the Receiver's 'surround mode' button.

The easiest way would be to reconfigure the buttons in the appropriate activities. Just choose a button on Pg1 (or 2 ...) that is not very useful to you in that activity, and swap it out with the surround function using the setup for your config. Remember to use the "activity", not the "device".
