Webinar Scheduling

Hello!  I am trying to set up a course for attendees that will be available multiple times a day throughout the week.  For example, attendees will have options to register for a 9am, 11a, 1pm or 3pm course. Is there a way to have recurring courses throughout the day?  I only see to set up recurring for daily/weekly/monthly.

If not, is there a way to give a customer access to a calendar that that has all off the available courses that they can choose from and register?

Thank you for your help!
