Hi Nicolas,
Thanks for reaching out!
You can do this by clicking the “Schedule multiple events” button on the event edit page, and then if you want to set specific dates for the event to recur on, go to “Once” and enter the date. You can add multiple dates by clicking the “Add more events” button (see screenshot). You could also select “Monthly” to set rules like “the first Monday of the month” (see screenshot).
You can add the box for info on teacher courses with Additional Fields, which you can configure under Events > Settings > Additional Fields.
I hope that helps! Please let me know if you have any additional questions.
