This is an Interactive View operated component for user friendly manual re-mapping of headers. Blocks double assignment of new header names, restricts dropdowns to unused values on refresh, includes an optional filter to better manage a large number of dropdown header values, includes option to append any unassigned new columns, includes option to sort new columns to match the list order (with old fields remaining in front), also includes backup and recovery or pre-mapping. The update button handles all saving and updating. Simply close the window and discard changes after each use use. If this component is used more than once in the same workflow, be sure to enter different log folder names in the configuration window. The log files have been moved to the main workflow file into a Header Remap Logs folder to avoid clutting the data folder. You can cut and paste prior log location over the new one to preserve settings, but I doubt it is use much since it was only uploaded yesterday.
