Shuriken particle System - change velocity by trigger

I am trying to replicate to a degree the wind zone system in terms of particles. I.e. I need to have mesh triggers that apply a certain velocity modifier to particles inside them. I am currently trying to use the trigger module of the shuriken system, but the OnParticleTrigger() does not seem to have any way to actually differentiate which trigger a particle is in.

If it helps, the actual purpose is to enable particles shot by the player to orbit around random shapes (spheres end up being very clunky).
