Outstanding Invoices Displayed in Calendar

Is there a filter setting to show only Outstanding Invoices in the Calendar view? I can filter a Calendar to display all Invoices, but I  care to see only when the Invoices which are not yet paid are coming due. I know I can call Outstanding Invoices from the navigation panes and see due dates there, but what I'd like is a quick Calendar view which graphically displays when Invoices are coming due, without the clutter of invoices which have already been paid.
