Hello,
I think I can help you out with this:
My client has a recurrent event/lesson that occurs every monday, wednesday & thursday. Is there a way to create one event out of this? So one event that is weekly recurring 3x a week.Otherwise I have to create 3 events.
I did a test and created a recurring event on Monday, Wednesday, and Friday(easily changed for Thursday per the settings below)
Here are my settings, you can change the dates to fit your events:

Another question: Can I have an event showing on the calender/month-overview but exclude from the list view?
We only have the option to do that with Recurring Events. It could be programmed using the existing filter, but that is beyond the support we can provide on the forum.
Let me know if you can get that working on the recurring event, also it must be done on a new event and not editing an existing recurring event.
Thanks
