Can't you just add a Field Called Attachments (Drop-down or Input of 2 Options TRUE AND FALSE) Default to TRUE when a Lead/Deal is Input into the System, then when Attachments are uploaded just have them Select TRUE.

Then search for All Leads with the Field Attachments set to TRUE.

Close.io is IMO the absolute best Dialer and CRM for the SALES PROSPECTING side of things. Marketing uses Close.io and we had a Programmer from Fiverr add a Feature that when the Status is Changed to FULL SUBMISSION the File transfers over via API to our CRM on the FUNDING SIDE.

When up for Renewal, the API's push it back to Close.io with the Label Refi Eligible for the Original Rep to Follow Up.
