It'd be cool to have a section that spans across the district(since courses are already) which can hold different students from different schools in one section owned by either the homeschool of the teacher or the district.

This way teachers who teach one section/curriculum to a group of students across the district can all be linked together for third party integration purposes.

Another great reason is for distance learners who are across the district under specific teachers. They all have the same "class" under the same teacher but have to be from different schools and the master schedule has to be done for each school for one class for a teacher. Also, third party integrations only go by school site and can't connect all the students into one class.
