Get a Target to move to, set the number to be the range away from the target you want to move to.
Move the unit more than 100 distance from the target. E.g. 150
Set the range of the target to move to, to be greater than 100. E.g. 140.
So, you have a destination with the number component set to 140. Move Unit with that destination ALWAYS moves to 100 range and not 140.
