I am trying to create a jolt transformation in NIFI , I have a JSON message with header, detail and line details as an array with line detail object.   Can we Transform Header/Detail JSON into Detail JSON One separate JSON for each Detail with  New Tag having flattened array of Detail Attribute values of "TRADETYP" and "TRANSPORT_CODE"   "TRADETYP_CODE_ALL" : [ "GR-BARGE", "EXP-AR", "CR-LCL" ]
