Can more special cross section be accessed in Geant4?

Physics Processes, Models and Cross Sections

Four main cross sections can be accessed according the example “/path/examples/extended/hadronic/hadr00”.
Can more special cross section like (p,n) reaction be accessed?

_Geant4 Version:_11.01

By the way, when using G4HadronicProcessStore class pointer to get the capture cross section of Isotopes, all capture cross section values are zero. the key codes are:
G4HadronicProcessStore* store = G4HadronicProcessStore::Instance();
xs = store->GetCaptureCrossSectionPerIsotope(particle,e,79,197);
