Is there any way I can mass complete tasks while saving the modifications made to the task?
If I understand correctly, you wanna use a button (somewhere) that when clicked, sets all of the statuses of a bunch of Tasks to "Completed" at once.
There is no way then to also "submit" those Tasks (or Task Forms) in the event that they are open (currently or in the future), or are not *really* completed.
Yes, I do want to be able to set the status of a bunch of tasks to "completed" at once. Once submitted, those tasks do not need to be open / edited again.
The current issue is that if those tasks were previously opened and edited then saved, this method of setting the status to complete does not carry those changes back to the list item.
