Yup, that is how you would have to tackle it. I too liked the ease of the press and hold feature. I put a 5 second press and hold on select button of the main menu of the remote that would take me to the hidden page with the clients equipment (AVR, TV...)

It was nice cause any job I walked into would have a backdoor to that page should you need it quickly. I haven't put it on the 890 but really should to still have that access to the hidden stuff.
