Validation of Reports Uploaded via Spreadsheet so that Incomplete Reports cannot be marked "complete" without mandatory fields completed

"If a teacher has used the Download & Upload functionality in Reports Wizard, they will be able to mark a report as complete, despite not entering a required grade or comment. This is because there is no validation process for the Import Sheet. "

This shouldn't be allowed to happen - the whole point of mandatory fields is that they are required and reports should not be allowed to be marked "complete" after import without that data included.
