Multiday Events (no recurrence)

It would be a great addition to publish events which are multiday events. users can buy a let's say tickets for a training which consist of three parts on different days. they can buy this as one event with one ticket. this is not possible at the moment. it's kind of similar to the now included recurring function. all parts of the training would be visible in calendar but point to one event. other event-management solutions have this feature it would make RSEvents even better...
