You can use a label that's somehow related to the function you're trying to perform. For instance, I control a C-Band satellite receiver which is not directly supported. One of missing lables is "satellite". So I use ANGLE, which for me is the "ANGLE in the sky" where the satellite is located. Anyway, you'd be surprised at how quickly you get used to using a different lable. Another approach is to use label location and ignore the text of the label all together. Use whatever method works better for you.
