Niagara particle collision question

Hello, everyone. I am new to niagara and can not figure out whether I can make particles change the behavior when they collide not with the mesh, but with each other.

For example I have an emitter with 2 particles (sprite renderer) which are randomly floating around. I want them to change velocity after(or if) the hit each other.

Or maybe there is some other way around for this type or effect?
