You can load a custom report to make changes to the existing criteria of the report. This makes it easy to add additional columns or filters to a custom report without creating a custom report from the Analytics custom report builder each time you need to make any modifications.
The Create a Custom Report page is displayed.
A confirmation dialog box is displayed with the “Are you sure you would like to load this report? You will lose any unsaved changes in the current report.” message.
The custom reports filter display and the table data is reloaded.
