When entering gifts, this will help me decided if the gift is a reactivation. At our organization, someone who hasn't given in 3 years go into acquisition, which has different coding. This will help me to quickly identify a reactivation without opening the constituent record.
As a workaround, could you use a User defined Business rule, with a query that pulls Constituents that did not give in the last 3 years? That would bring you a pop up window in batch and you would not have to open the Constituent record.
