How to spawn, move and have my actors connected with beam emitter

hello,
I would like to get back to my old project (which connect each spawned overlaping actor with beam emitter)

and make it even better. All I need to make is letting move to all of my circles. This is not that hard since I can set vector and update transform every frame,

but my emitters here is based on location so my circles move but beams stays same position (have same source and target points and these are not updated).

Here is my blueprint with not-moving actors

Is there any way to make it?
thanks

another bump
