Does anyone know if its possible to set each input to the same volume setting? Right now, in my 2015 IS 350 AWD w/Mark Levinson system, each input has its own volume stored in the system. Therefore, when switching from one input to another, the volume might be completely different.

Is there no way to set it so that when I adjust the volume on one input, it uses that same volume setting on all other inputs?

Thanks
