As it stands, if a learning is enrolled in a course with a due date, that course shows on their calendar within the learner dashboard.
However, if there is an automatic enrollment after a set amount of time or expiry of certification, that does not show on their calendar because they have not technically been 're-enrolled'
From an admin, it would be nice to see a calendar that included re-enrollment dates of courses to make sure that future trainings are scheduled correctly
