RoleCenter delete additional Actions


when I add the “Bookkeeper Activites”-Page as a part to my Rolecenter I get four more Actions in the left pane. These are “Purchase Invoices Due Today” or “Vendors - Payment on Hold” but not all of the staples in the added Page.

How can I delete these Actions in the left pane? They can’t be customized with the user customize functionality in the RTC, too.
