My approach is to binding a key to strafe left or right on each of my 5 characters. This key is bound to a non standard key for each character. When I press that, follow breaks

I take that a step further and have 1 slave go left, 1 right with a key press, then 2 move left and 2 move left with a different key. Doing this, with 2 key presses, my 4 slaves spread out.
