In the Course Activity report when you select multiple users you can select the Edit Multiple button fom the Mass Actions menu to update fields such as course status, score, or credits for all the users selected. It would be very helpful if the course expiration date field was included here as well. This way if/when the exipration date for a course needs to be bulk updated for a large set of users it can easily be accomplished with the Edit Multiple option.
It would be great to add the ability to edit the due date here as well....
