Allow users to sort requests by scheduled date & submission status
All saved and scheduled requests are currently listed in Outstanding Requests, and there isn't a way for users to easily sort out just the requests for their upcoming appointment. There also isn't a good way for them to view when they have an appointment coming up, short of going into each request (and they may have requests scheduled for different days). It would be good if the patron could see the dates they have requests scheduled and the requests scheduled on those dates, as well as be able to sort Submitted vs Saved requests.
