Adding Team in Menu

With the demo data in, I see that the main menu includes an area for teams. (Found in the menu: Teams > Teams Tab > “Devils Brigade” & “Skywarrior”. The problem is that when I go to that section on the main menu editor I am unable to add additional “Team” items as it does not appear as an option to drag from the left. How did you get the team selection in the main menu? Is this something I cannot do?
