Once you select the Group name, there will be a pencil and paper icon on the right hand side that pops up with "edit" when you hover over it.
Scroll down to the grey tile bar for Benefit Advisory and you will see boxes underneath for Advisor and Support Person (if you cannot see this click the round + side to the right of the title bar).
Choose your name from the drop down box.
Scroll down to the bottom of the page and click save.
The changes will now be reflected on the Benchmarking Reports.
