How to Show Only Selected Headers in CSV Output While Keeping All Data in SnapLogic

Hello! I have a scenario where a Mapper snap is generating 10 fields and producing 5 rows of data. However, in the final CSV output, I need only 7 of the headers to be visible. The remaining 3 headers should not appear in the CSV file, but their corresponding data should still be included in the output. How can I configure the pipeline or the CSV Formatter snap in SnapLogic so that only selected headers appear, while still keeping all data values in the correct order? Any guidance or best practices to achieve this would be appreciated.
