Repeating classes with custom timing

I need to create a course which includes 3 x 1 hour sessions each day (morning, afternoon, evening), over 3 days (9 sessions in total). The days will usually be consecutive (e.g. Tues-Thurs), but sometimes they might be Mon, Wed, Fri, for example. Clients need to sign up for the course as a whole (I only want them to be required to make a single booking, not 9 separate bookings), but they need to be placed in all 9 sessions. They need to see the times and days of the sessions when they book. I thought using the scheduler feature would be best but it doesn’t seem to allow that level of customisation for classes. Is there a way to do it? Would I be better making each course a product instead?
