Spawning an actor and then moving it in a loop.

As the title said, I need to spawn an actor and immediately make it move along a spline, and then, when the actor hits a trigger volume, spawn another instance of the same actor, and again make it move following the “tail” of the first one, and keep doing so indefinitely.

Right now I´m stuck in making the actors spawned after the first one to move along the spline following the first, with what I have so far they just stay in place. Maybe if I could find a way to make the “set actor location” node to reference the newly spawned actors, but I can´t figure out a way to do it. What do you guys think?

Thanks a lot!
