You can pin any report you find on the More Reports screen to the left navigation menu. Pinned reports will appear in a drop-down menu that is labeled by the kind of report it is. For example, a pinned Performance report will appear within the Performance drop-down menu. Most drop-down menus (e.g., Operations) will not appear in the left navigation menu until after you have pinned a report of that type.
From the left navigation menu, select Reports → More Reports.
Find the report you want to pin to your left navigation menu.
Use the filters at the top of the screen to assist your search.
Hover your cursor over the report and select Pin to pin the report.
