Devialet Chat

Using the Devialet in bypass mode (cinema setup) I realized when doing an Audyssee measurement that I had to switch the phase on the Devialet! (this is actually the first time that I came across a usage scenario for this setting :-) )
So everytime I switch to "Line In" source I would love that Devialet remembers my Phase-Setting (-)
Unfortunately it seems everytime there is the default value (+) and I have to manually switch it.
Any ideas?

BTW: the setting ICM is remembered correctly per source.
