[ndnSIM] NACKs in ndnSIM2.0?

I am trying to port a forwarding strategy, which I have implemented in 
ndnSIM1.0 to ndnSIM2.0. I have looked through the documents and API 
specification, however, I don't understand if and how the concept of 
"NACKs" is supported in ndnSIM2.0. Can someone give me a hint how to 
implement the following in ndnSIM2.0:

Assume a forwarding strategy decides to proactively discard an Interest 
message. What would be the best way to propagate this information to the 
requesting neighboring? In ndnSIM1.0 I have used the build-in 
NACK-response from the NACK-Strategy, which responds with a NACK-message 
once all faces have been set to "waiting in vain".

Best regards,
