Often times, when there is an unfortunate need to change the dates in 'Available to enter until' for many columns of multiple gradebooks much later, it is insanely time consuming to change the dates one by one. To simplify the process, it would be great if this feature can be considered so as to change those dates of multiple columns in just 2 or 3 steps like how the unlocking/locking data entry of multiple gradebooks feature was added recently. Thank you!
