Hey @Victor,
There is unfortunately no way to do this unless you were to write some extensive custom code 🙁 We unfortunately cannot help with custom code projects, but we do keep a list of highly-reviewed developers for hire here if you are interested in hiring someone to build these features for you → http://m.tri.be/18k1
If you’re a bit code-savvy yourself, or comfortable exploring and learning with some tinkering, you might be able to get pretty far along by first reading our Themer’s Guide to learn how you can customize the display of events on your site → https://theeventscalendar.com/knowledgebase/themers-guide/
Once you have a grasp on that, you can head to your plugin files for The Events Calendar and navigate to this folder there: /src/functions/template-tags. This “template-tags” folder has a bunch of files with a bunch of publicly-usable functions that you might be able to then use to show different markup based on the organizer.
I’m sorry that I’m not able to provide example code here; as I mentioned, this is a bit of an involved customization 🙁 But hopefully the information here is helpful regardless.
Let us know if that’s the case, and/or if there’s anything else I can help with!
Sincerely,
George
