You may try with the general particel source (/gps macro commands) and its capability to define input spectra trough histograms.
For more details you should look in:
1) The gps examples
2) In the user guide http://reat.space.qinetiq.com/gps/new_gps_sum_files/gps_sum.htm the description of commands /gps/ene/type /gps/hist and also the examples http://reat.space.qinetiq.com/gps/examples/examples.htm
Note that since g4.9.4 a new gps macro command /gps/hist/file your_file_name allows the user to specify arbitrary energy distribution by supplying the data points in a 2-column (energy<in MeV> and flux) ASCII file. I never tried this command myself but I believe it should work.
