Yes this is possible and could be helpful if you've got a big room with a couple of different entrances or gathering areas or the application is a room/zone where more than four favorites is desired. Please read below to assure the system will function as desired.

Add both keypads to the same zone in System Configuration.

You may set the favorites on each to be the same or different.

Regardless of whether they are the same or different at setup, a press and hold on any favorite button will update that button on that keypad only. The other keypad in the room will be unchanged.
