The “easiest” way to do it might be with the Linked Tools behavior. It’s similar to the pathfinder but uses linked objects. There’s a bit of a learning curve. IDK if you’re familiar with the behavior. It requires setting up the links but then it’s fairly automatic.

To have different paths you would need to make some changes like using a different animation of object variable for each path and then link those tiles and pick them for the move.
