On mine you can enter "manual leveling" mode and retract jacks that way.
Mine also fully retracts all jacks when you use the auto-level function. Sometimes I end up manually adjusting the jacks after the auto-level has done its thing, or if I need to tweak something after everything has settled.
In manual mode, I haven't found a way to control each specific jack though. It only "raises or lowers" the front/rear/right/left which may mean extending or retracting pairs of jacks. There very well may be a way, I just haven't every messed with it enough to figure out if it's possible.
