I have a Sales Pipeline base, and have set up an automation to run based on a change in deal stage (to "closed-won"). This creates a new record in my Master Customer List airtable.

 

When I filter my Sales Pipeline base and then unfilter, the automation assumes that the unfiltered "closed-won" records are new and therefore should create new records in my Master Customer List airtable. This is causing issues with mass duplications.

 

Is there a workaround for this?
