Particle System Trigger

Is there a way to use the trigger (in the particle system) without having to define the Colliders first and find out what my particles touch?

I would like to visually create the sound propagation (for this reason the collision module is not suitable, it does not interact with the colliders), but I cannot include all the enemies in the list of colliders.

Thank you

Ey pleeaase someone need to find this out!

Did anyone found this out ?
