The new update to the rosters import file requirements necessitates that each row have a valid email address associated with it. In theory, this is a good idea. But in practice, it is causing more work for schools/districts who have classes that are not yet assigned to an instructor yet (for example, classes currently being covered by a long-term sub). Previously, we were able to upload the file with "Staff" listed in the instructor column. Now, I am forced to manually change 300+ rows of data to connect each student in these classes to the appropriate instructor account. The previous structure was more efficient as it allowed me to go in and assign instructors to these classes after the import was complete. Please, please make this easier on us!
