Our libraires use the Polaris patron record 'Use Single Name Field' setting for institutional records (schools, businesses, ILL lending) and patrons with mononyms. The Single Name currently maps to the LX Starter last name merge tag. Libraries generally just use the First Name merge tag in notices, so no name appears in notices for patrons that use Single Name Only. It would be really helpful if there was a way for these names to map to the First Name merge tag!
