None Forcing a Reaction

      Is it possible in Geant4 to force a particular reaction in a volume, like you can in MCNPX?

What I have is a simulated Lithium Fluorine Target in a 1.94MeV proton beam. Due to the extremely small cross-section of the target reaction (Li7(p,n)) in a straight, unbiased, run I get 1 neutron produced every three million protons. As I wish to study the resultant field of these neutrons at a point 100cm away this neutron yield becomes untenable.
