extend NBAR classification by PDLM

I have added a new .pdlm File from the cisco.com Website to my router to classify the SAP Traffic (sap-msg and sap-app). I have updated the config to load the pdlm File and all of that seems to work fine.
But on the NetFlow Analyzer I can't see anything of those changes. In the list of the supported Protocols it is not mentioned. Do I have to add any extensions to NF Analyzer to recognize that or is it not possible to classify any other protocols than the ones on the website manageengine.adventnet.com/products/netflow/help/nbar/nbar-supported-applications.html?

Another question: Is it possible to rename the custom-01 through custom-10 nbar classes to something different?
