At this time, there is unfortunately no built-in automated method to retroactively filter out or clean duplicate survey submissions without manually reviewing or exporting the data.

Having the ability to automatically identify and exclude duplicate survey submissions for reporting purposes would be extremely valuable. Duplicate submissions can significantly skew reporting and dashboard data, making it difficult to accurately track true opt-in numbers, new leads, conversion rates, and campaign performance. This can also create discrepancies between funnel statistics, contact counts, opportunities, and automation reporting, leading to confusion when analysing results.

Could the development team please consider adding a feature that allows users to filter reports by unique submissions, unique contacts, or first-time survey completions only?

This would greatly improve reporting accuracy and reduce the need for manual data cleanup and exports.
