[ndnSIM] N consumers M distinct producers

Is there a way for a single consumer to generate requests in a zipf
distribution for multiple M producers, where each producer is responsible
for a particular prefix? I would like to have M producer nodes (1...M),
where (except for intermediate caches) producer1 is the only producer which
can satisfy a particular interest /producer1 or /producer/1, producer2
satisfies /producer2 or producer/2, etc.
