My client wants to use the scheduler module to allow students to sign up for weekly or biweekly appointments. Students may want to sign up for multiple appointments in advance so they can know their schedule but currently this is not possible. This has also been asked for in the scheduler forum by someone else:

What would be useful to have is instead of radio buttons have checkboxes and the module could be configured to set a specified maximum number of slots a student could choose at one time.
