Does anyone know how to make a particle trail for multiple projectiles at once?

[CosmogonicToast]

I'm making a game where there is a shotgun that shoots multiple projectiles and i want them to have particle trails but all of the methods to make a trail only work on one projectile and i can't find any guides on how to do this so if anyone knows how to do this PLEASE tell me how.

maybe try 'repeat' block to shoot multiple projectiles/raytrace, and randomize the projectile/raytrace direction and do trails for each projectile
