We offer "self-paced" courses through Canvas Catalog.  This means that enrollment is continuous and the course is automated.  Every student has a different set of dates for their section, depending on when they enroll and what the time limit is for the listing.  Many of our students enroll in the course, but forget to complete it by the end date.  It would be so helpful if Catalog could be set to automatically send each student a notification a week or so before their end date.   It would say "Hello there, This is a friendly reminder that your time limit for the ___(name of listing) course will expire on ____ (end date).
