It would be very helpful if enrollment keys could be set as inactive the same way you can with a course. We use enrollment keys to deliver training purchased by external customers. Sometimes enrollment keys are no longer valid (cancellation, refund, change request, etc.) and we want to close access to the key. For data tracking purposes we do not want to delete these keys. It would be very helpful if keys could be set as inactive for this purpose. It would also make reporting on the enrollment keys easier as we wouldn't need to manually filter out any of these closed keys.
