Slimline 2 Remote - Reprogram Buttons

[wireless]

Is it possible to reprogram a button on the Slimline 2 remote for another function? I'd like to have Closed Captions as a single button to press rather than having to go to Options, scroll down, enter, scroll down or up, enter, etc. I never use the Apps button so that would be the likely candidate to reprogram.
Yes I know that I could go out and buy a Logitech Harmony remote ...
