A question based on
"There is nothing inherently unique in that output spreadsheet to identify a unique request "
Do you/could you include the assessor's name or ID in the collected spreadsheet? Along with other identifying info ( to be used subsequently for overall identification of unique records).
I'm not sure if you are saying there can be no unique identification OR currently we have no means to uniquely identify records in that output spreadsheet or the database.

Is that because @jdraw specifically switched his text color to black there? Maybe the "none" or "remove formatting" option would be better in this case as it should then follow theme rules.
