Hi Bak!
Thanks for getting in touch! Let me help you with this question.
When previewing your import, you can select the post status and a default category for the current import.
If you want to specify additional fields, you can use CSV imports to assign tags, image, content and custom fields. Here’s a guide to CSV imports with some examples you can download to run some tests > https://theeventscalendar.com/knowledgebase/csv-files-options-and-examples/
Finally, you could also customize how the events are imported but would require some custom coding, which we can’t give support for.
I hope it helps. Let me know if you have any follow up questions.
Best,
Victor
