M50: how to store the position of the value slider?

[TheFe]

I own a M50 and I was wondering if I can store in a program the exact position of the value slider.

I'll explain better: in a song that I play, I have to change two sounds, Detuned Sawtooth (stored in B0) and Classical Choir (stored in B1). With the Detuned Sawtooth I keep the value slider at the maximum value, so the sound plays like a double octaver. My problem is that when I switch to Choir and then back to the Sawtooth, if I want to have the octave effect I have to move the slider down and up again.

Is there a way to save the position of the slider so I won't have to move it every time?
