Question about collision model

Installation | How to |

I have a question about setting up the contact model. Usually the particles we are simulating have two or more types, so we need to set the coulomb and rolling friction coefficients between particle 1, between particle 1 and particle 2, and between particle 2. As shown in the figure, the parameter setting here can only set the coefficient for particle-particle. How should we handle multiple particle types?
I’m looking forward to your help.
