The new(ish) bulk waive options in Leap are extremely useful, but library administrators often want to waive charges of a certain amount - usually "waive all charges of less than X dollars." The current interface, however, doesn't allow the user to specify an amount for the charge to be waived. This would be very useful and would avoid the need for creating a SQL statement to identify such charges. The scenario of waiving all charges greater than a given amount is less likely, but if you're adding the ability to specify a maximum, why not add the option for a minimum, too? :-)
