How to edit section headings
Navigate to the section within the report itself where you'd like to edit the heading.
Then, within the heading on the page itself, modify the text in any way that you wish. As you can see, changing the heading on the report itself also updates the heading name in the left-hand side navigation, under the "Report Sections" heading. This will also update the name in the report's table of contents, if you choose to include the TOC.
