I have a number of students in every class that require special accommodations, such as extra time.  At present, I have to go into each quiz to grant the extra time.  It would be great to have a course-level setting where I can grant 50% extra time on Quizzes (or other course components) for students A, B, and C, and maybe 100% extra time for students D and E.   This way, regardless of the length of a given quiz, the additional time will automatically be granted up front based on the percentage set.
