Can you use this same set up to create a circular "holding pattern" for air units? Say you have a Wraith that doesn't have any active commands or ques. If it was to sit stationary, can you use periodic movements to have that unit perform a closed loop circle?
Also, could you use this same effect to force all air units (with no given commands) to move in a straight path until you give them a command? Like, when they are created they just fly straight. You tell it to move a different direction. That air unit will face that direction and then continuously move in that direction, *including* flying over the point you clicked on?
