Add the ability to create a new Planner Page. This would allow a Flow to generate an entirely new Planner Page associated with a specified O365 Group.
Would be good if you could get the categories in Outlook Tasks to Flow by creating new Plans in Planner with all the Category names appearing as new plans. And then automatically populate the new plans with all tasks in Outlook Tasks under those categories. It would be better still if Planner simply synced Outlook Tasks to Planner creating new plans for each category and putting the tasks under them.
