Hi Scott
A lot of players just assign the registrations to a footswitch (They set up all the changes of the song in the correct order in the registrations) and use this to step through as the song progresses. (If you also assign fills etc to a footswitch, there is little need to take your hands off the keyboard at all)
Another option
