When using mass add to change the GLO for student records it's changing it for all enrollment records, not just for a specific entity. With needing different GLOs for EC, EE, PS, etc. it would be helpful if you changed the GLO for only that entity record, not all. If you ran it from 000 it could/would change the GLO for all records. Having to hand change all records to EE or EC or HK on individual enrollment records it time consuming and a hassle to be compliant with ed-fi.
