I would like to reveal an Online Course only after a learner picks their session in their ILC.
Two workarounds that don't quite fix the problem:
Right now learners that meet a rule can see an ILC in the Featured Courses or Catalogue without enrolling. Clicking "Choose Session" will enrol the learner, triggering whatever post-enrolment is set, revealing another course. In this case, both the ILC and the online course need to be set to "Featured". Featuring all courses is not ideal. Using the catalogue to help with post-enrolments is also not ideal as it will clutter the dashboard.
One solution: Integrate ILC sessions into Online Courses.
