i have running counter say port.packets and i want to calculate the cumulative sum on the buckets path of the derivates normalised value by units instead of the actual derivative value .

Usually cumulative sum is taking the name of the derivative buckets path , is there any way I can provide the buckets path as normalized value ?

example aggeration

```auto
{ 
"size":0,
 "query":{ 
   // some query 

},
"aggregations":{ 
  "termsAgg":{ 
     "terms":{ 
        "field":"portIdToClusterId",
        "size":1000,
        "order":[ 
           { 
              "_count":"desc"
           },
           { 
              "_key":"asc"
           }
        ]
     },
     "aggregations":{ 
        "dateHistogramAgg":{ 
           "date_histogram":{ 
              "field":"timestamp",
              "missing":0,
              "interval":"5m",
              "offset":0,
              "order":{ 
                 "_key":"asc"
              },
              "keyed":false,
              "min_doc_count":0
           },
           "aggregations":{ 
              "maxAggportrxpackets":{ 
                 "max":{ 
                    "field":"portpackets"
                 }
              },
              "derAggportrxpackets":{ 
                 "derivative":{ 
                    "buckets_path":[ 
                       "maxAggportrxpackets"
                    ],
                    "gap_policy":"skip",
                    "unit":"1s"
                 }
              },
              "cumSumAggportrxpackets":{ 
                 "cumulative_sum":{ 
                    "buckets_path":[ 
                       "derAggportrxpackets" // I want to take the normalized value instead of directly derivative
                    ]
                 }
              }
           }
        }
     }
   }
 }
}
