could be added an hotkey to turn on/off the replaygain ?

[gaiastar]

Hi
in musicbee there is an hotkey to toggle replaygain ,but it does switch between  disabled  to  smart to  track to album and to disabled
in short if I want to turn on/off i have to push several times the same keyboard hotkey
would be nice have the possibility to turn on/off the replaygain like eq or dsp
thanks
