Auto-complete stages/activities/tasks when SuccessCycle is complete

Currently, if you complete a successcycle without checking the box on any line item with a due date, you still continue to get nasty grams about being overdue, even if you have selected to complete the successcycle. Can we either 1) require that all of these boxes be checked to move to complete OR 2) autocheck those boxes when choosing to complete a successcycle?
