register one event, use/show many times (for training courses)

Hi,

I'm looking for the possibility to buy a ticket for an recurring event (aerobic course, training course, medical course) only one time and use/show the course as often as defined.

For example medical courses: register/pay till the course start und visit the course as often as allowed.
Register is only possible for the first event, the other defined dates are only shown as item in the calender without the possibility to register.

Many thanks.

Bob
