Ming, I dont know exactly what kind of info you wanted to modify or attach to an Interest packet, another option besides Spyros suggestion could be carrying your info in NDNLP-equivalent way.
(forgive me: I do not know whether ndnSIM has NDNLP, Spyros does)

Because the forwarder is not supposed to change the packets at that point of the execution. I would suggest if you want to change Interests, create an application that could do that.
