We would like to be able to cap the number of sessions someone can sign up for when using the multi session enrollment feature. We have a 2 day course with limited seats per session and don't want someone to be able to enroll in multiple sessions just to hold a spot, or forget to unenroll from one session before signing up for another. We are currently monitoring the enrollments for each session by running reports to make sure someone isn't registered in more than one session for day 1 or day 2 of the course.
