In doing an export, when I specify an Individual Relationship to export, I'm given the option of specifying relationship types and class of fields to pull. However, in the Class of tab, I cannot specify for the Export to look only at the Primary Alumni Information marker for the class of. If I specify class of 2016 and a relationship on that record has the Class of 2016 as their Class of for their College record (not our school and not the Primary Alumni Information), it will show up on the export.
