PhysX collision interaction from different events - Possible?

[d4rk3lf]

Well, I am sure it's already possible, I just didn't explored it yet too much (simply because I usually use PhysX bind in this situations, and therefore it's not moving anyway, before it being hit)
For example, i am pretty sure it's possible to test group of particles with property test, a distance (neighbor) with other group of particles, and just send them to activate/deactivate.
