Just put the flat sequence inside a while loop in Periodic Tasks. Right-click on the edge and add frames as needed.

Each of the "wait until" steps should be implemented as a while loop inside one of the frames. Put the code to read a joystick button or limit switch inside the loop, with the logic set up to stop the loop when the desired condition occurs. Also add a 5-20 millisecond Wait inside the loop, to keep it from running as fast as possible and starving other tasks of CPU time.
