Flip Through Only Favorite Channels?

I have searched and am not able to find how I can set up my Xfinity Remote so I can flip through only my favorite channels. My old Dish account allowed me to change the guide view, which also controlled when I went up or down a channel. Currently, it stops on unsubscribed channels -which is a waste of time. How can I fix this? Asking because my 88 year old Mother keeps getting hung up when it stops on an unsubscribed channel. I am not streaming, I have the actual DVR box.
