You might want to use biasing for that. Have a look at the
generic biasing examples (examples/extended/biasing/GB01 and GB02).

I am not sure I understand this part of the question. Do you want to
have different physics lists (i.e. processes) by particle type, or by
volume? The former case is trivial -- a physics list is just a
collection of process-particle associations. Can you please give more
details about what you are trying to achieve here?

Regards,
Davide
