Additional roles can be assigned right here. Click 'Assign more roles'. Select the role to assign and to add more than one role click 'Assign More'. Once the roles have been selected, click 'Confirm Assignment' and the user account will update with the new roles.
To un-assign roles in the user account, click on the 'X' next to that role and confirm it. The account updates immediately.
