Hey there!
Adding more options or any other design tweak is possible, but is unfortunately something that would require custom coding.
We are not able to help with custom coding, unfortunately, as elaborated upon 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 → https://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).
Sorry to bear this news!
