I am interested in using this and happy to pay for it if it will do what I need. We have a sign-up system for events using google forms and scripts and get a lot of unintended resubmitted duplicates from iPhone users and Apple has made zero effort to fix it over the last year. Would this add on be able to check for duplicates immediately upon submission before the script starts running? If a duplicate is found I would just like to break the script so it does not run and begin sending payment instructions to the submitter.

The single most essential and really only feature of the add-on is locked behind a paywall.
