Reporting - Updates

edited 12/09/19 in Smartsheet Basics

Hello - I'm tracking ~40 different sheets on a monthly basis for updates. Is there a reporting mechanism for automatically updating a report with an update date or check mark when each of these sheets is updated? Right now, I just create a workflow to notify me if something has been added/changed on each of the sheets, then I manually go in and place an X that the sheet as been updated on a new sheet.
