Add a defined date for late assignment submissions
Example: An assignment has a due date of November 15, but I allow late assignments (with a penalty) for one week following the deadline. I would like to be able to select "Allow late submissions" and then have a choice for how long the late papers can be submitted. In this example I would mark Nov 22 as last day for late work. The system would mark files from Nov 16-22 as late and on the 23rd would not allow any more assignment uploads.
