Change displayed name of Squeezbox Radio

[SvenSchiffner]

I have multiple Squeezebox Radios in my home. These are identified by MASS as controller with a hexadecimal number (maybe the MAC). In MASS itself and HA I can change the name easily. But in the Radio itself it still display the "controller ". It would be very nice (mainly cosmetic) to change that name.
Maybe this is also problem with squeezelite players, but I never used them.
