I often use the Superplayback, both in structured and in busking situations, and it's kind of a bummer that pressing any other "select" playback button overwrites the contents of the SuperPlayback.
I'll make a stack of FX for a group of lights, put it on the SuperPlayback, and set the 2 faders for FX size and FX speed, for instance. Love that, gives me all kinds of control in live situations, but when I want to adjust the speed of a chase or FX on another cuelist by pressing select and using the wheels to get where I want to be, when I let go of the "select" button, the cuelist last edited remains the one loaded into the SuperPlayback.

Is there any way to set the desk to revert back to the cuelist either "loaded" or dragged onto the SPB...?

The only thing I can think of is the Lock button on the SP but that won't let you switch to anything else.
