Yamaha MO - How can I avoid having to move all the sliders up and down to reset the volume.

I perform regularly with a couple of different bands and have so far stored each song in its own 'Perfomance' so when I switch to a song (on the Yamaha MO) I have the correct combination of instruments in their approriate zones etc. As I am playing I usually need to fade different sounds in and out. The problem is that when switching to the next song, the current position of the sliders do not represent the stored volume settings in that performance. This results in having to move all the sliders to the top and then down again to reset them so the volumes in this perfomance can be controlled.

I have to do this between every song during every gig and every practice. Is there a better way....??
