How to delete FlowFile's from Data Provenance in NiFi?

[#1]

I want to delete some files that are in my NiFi Data Provenance. I have a processor, DetectDuplicateUsingFileName, that uses a DistributedMapCacheService/Server, and when I right click the processor and click "Data Provenance", I see a list of FlowFiles. I want to delete some of these so my DetectDuplicate doesn't detect those files, how do I go about doing this?

There isn't a processor to do this, but this HCC article covers how to create a script to accomplish this: https://community.hortonworks.com/questions/110551/how-to-remove-a-cache-entry-identifier-from-distr...
