We have got a use case of quizzes consisting only of essay questions with file upload responses. The files are then downloaded for offline grading. Then we need to get the filled grade lists imported.

Currently, there seems to be no way to import grades of quiz questions:

• In "Quiz administration > Results > Grades", I only see "Download table data as", but no upload function.
• When trying to import via "Grader report", the setting "Grade item mappings" only lists the whole quiz, not the separate questions.
