Change input labels

I have a Marantz 2250b and the labels on the input dial are not related to my system at all. For example my phono stage goes to Aux and my DAC goes to Tape 1. My DAC has three inputs (computer, airport, and chromecast) labeled 1, 2, & 3. So no indication of what is what.

I can keep things straight because I set it up by my family gets frustrated.

Are there any methods for re labeling the faceplates of these devices that don’t look like $#! +?
