Can SAM be set but default to disabled?

[Axel]

As per the title really, I'm using SAM less and less but like the option sometimes.

The question is can it be set for the appropriate speakers and percentage, but default to off (disabled) at startup?  

I'd like the convenience but can't be bothered to turn it off every time.

I've had a tinker with the Configurator and no, I don't think it's possible. I guess the best way is to designate one of the buttons on the remote to toggle SAM on or off.
