Hi Andreas,
Thanks so much for reaching out again!
You can create a large number of events via CSV. Here are some examples of how to set this up:
https://theeventscalendar.com/knowledgebase/csv-files-options-and-examples/
Since recurring events aren’t currently supported with Event Tickets Plus, adding the tickets to these events may be tricky, unless you create the series as a recurring event, and then individually break each event from the series in order to create individual tickets.
Otherwise, your best bet is to create 200 individual events with individual tickets via CSV and then import the file.
Let me know if you have any other questions on this topic!
Thanks,
Jaime
