Save time with saved reports
To save yourself time, once you've created a report you can save your report and then access or modify it later. Saved reports enable you to customize and save the specifications for a report for quick access in the future, so you can avoid the lengthy process of generating the same detailed report over and over. You can save preferences like date range, any variation of channels or aggregate data, and whether you'd like to view page impressions or ad unit impressions etc.
