nifa and nwfa not as tracers, but can be outputted and be seen by mp_thompson

HI, There:

I have added mraerosol  similar to ltaerosol by setting ltaerosol as false  and mraerosol as true,   and  nifa and nwfa are calculated and not as tracers.  but when ltaerosol is false, nifa and nwfa cannot be seen by mp_thompson because they are optional variables. My question is how to setting nifa and nwfa as non-optional when ltaerosol is false? The other issue is how to put these two variables in Statein(nb)%qgrs? so they can be outputted properly

I have performed an experiment by changing nifa and nwfa from optional to nonoptional in mp_thompson.F90, but receive an compilation err as "Exception: Variable mass_number_concentration_of_hygroscopic_aerosols in mp_thompson/mp_thompson_init is not an optional argument, but listed as such in the CCPP_prebuild config".  Where is the CCPP_prebuild config and how to make changes on it?

Thank you
