Currently LendingReminderDaysBeforeOverdue and BorrowingingReminderDaysBeforeOverdue adding value of 0 will disable lending reminders. However, in the other keys for scheduling the overdue notices, a 0 value will send the notice on the day the item is overdue.

It would be helpful if these keys worked the same way and all allowed the ability to disable the notice if you want to send less than three notices with the automated service.
