Hi @JimJewell,

Unfortunately, I don't think that's possible right now.  The export feed from Canvas, as you've noted, includes all of a user's courses plus their personal calendar.  There is an idea theme for calendar syncing and scheduling, but I don't see something like this in that theme right now.  You can submit this as an idea to have it considered for future development by Instructure if you'd like.

Hope this info helps a bit.
