I would like it to be possible to add a "reapeat" function on plans/tasks in Planner. Instead of making New tasks every month, week, you should be able to repeat the task With whatever interval you desire. "This task repeats itslef every Monday", or "first Wednesday of the month". Like Meetings in Outlook, where you can choose to repeat a Meeting.
