Daily export to Apple School Manager from Student Information System - Teacherease/SchoolInsight

Our school district is switching school information systems to one called SchoolInsight (sometimes known as TeacherEase.) This new SIS does not have a built-in export to update Apple School Manager. I've been on the phone with their tech support and it appears that getting this done is going to be very clunky; if possible. I wanted to reach out and see if anyone already has this in place. Thank you.
