Hi Benjamin,
Thanks for reaching out. The features you are trying to implement are possible, but would unfortunately require many code customizations to implement. 🙁
We are not able to help with custom coding. Read more here: https://theeventscalendar.com/knowledgebase/what-support-is-provided-for-license-holders/
So to implement the features you describe, you would have to write that custom code or hire a professional developer to do it for you. We have a list of great developers here → http://m.tri.be/18k1 (and have no affiliation with any of these folks—they’re simply some well-respected names in the community that we’ve compiled to share in situations like this one).
Best of luck with your customizations!
George
