You can't change the built in reports, so you have to copy the report before you can make changes. Use the copy button to copy the build in analysis report.
Click on the settings tab and change the name of the report. By default the name will start with "copy of..."
Run the copied analysis report as usual, select any parameters that produces some output. At this point we don't care what data is displayed, we just need a report to edit
Right click near the top of the report list view and select "show field list"
Drop the fields in the correct area of the report, just as you would if you were creating a new analysis report
Click save and close when the report is complete
The run the report again to review your results.
