In RE when adding a tribute to a gift in batch there is the option to choose the acknowledgee. This is helpful when a donor specifically wants one family member to be notified of their gift as sometimes multiple family members as listed as acknowledgees on a memorial gift tribute. In CRM only the first acknowledgee added to CRM is listed on the donor acknowledgement letter and this causes errors since you are not able to choose the name for the donor letter. All family members are notified of the gifts made however you can not pick and choose who will be notified.
