This would be very beneficial for us to know when an addressee was last looked at by our development officers. We currently have no way to know whether or not an addressee was last reviewed yesterday or 5 years ago. This would greatly benefit us when pulling reports with a recognition addressee (for donor walls or annual reports for example).
With a date field we would be able to monitor addressees and have our development officers review addressees that had not been looked at in a year or more.
