Updating part of a JSON Document

Mapper output is shown below. I would like to update the InstrumentIdentifiers section in the JSON with the Tickers section.

In other words, the Array of JSON fragments under Tickers should come under InstrumentIdentifiers. Second Image shows the JSON structure that is desired. List of Tickers in the final output may seem different but has been truncated to fit the screen shot

    with a mapper you can use the expression: $Tickers and target of where you want to map the value to, which in this case is: ExtractionRequest.InstrumentalIdentifiers
