Adding extra quiz attempts or extra quiz time for individual students in a very large class is a real pain because there is no way to filter the student list on the Moderate Quiz screen. If the course has 2500 students, it takes entirely too long to click each page of students until you find the name. You just have to start guessing which page they are on and click through them until you find the student.
It would be amazing to have a filtering option like the one on the "People" page of a course.
Having a dropdown to filter by section would be pretty great too!
We tried using the API to add quiz attempts but the endpoint is still in beta and it currently doesn't work at all.
