That is not correct.
I have programmed my URC MX850 so I can switch from 7.1 to optical to coaxial at the touch of a button.
This is really good for comparing different decoding.
All I did was set up macros with different names.
Like for 7.1 it is the "movie" button on the remote.
For optical it is "Oppo" and for coaxial it is "DVD".
Very simple to do.
