Turn of pathing/collision

Hey, i'm making a spell which targets an unit and swings it around you in a chain. The idea was, that enemy units hit by the chain should then also be swang around. It works fine, but the movement is really crappy because of the units pathing. If I give Locust to the units everything works fine, but i can't remove the locust ability later, and i'm not sure if i'm doing anything wrong.

Is there a way to remove pathing/collision of a unit?

SetUnitPathing takes unit whichUnit, boolean flag returns nothing should disable the units pathing if set to false.

EDIT: Found the GUI equivalent:

Must have missed that one.
