Hey Roberto,
Thanks for getting in touch!
That’s a really cool idea! I think the best way to get started with a customization like that is to look into connecting other post types to the Events post type.
We actually have a guide on how to do this:
https://theeventscalendar.com/knowledgebase/abstract-post-types/
The idea is that you can create a new post type and register it to your theme, then connect it to Events so that you can have a new way to create Speakers, Presenters or any other post type to events just like Organizers and Venues.
Will that help get the ball rolling for you? Please let us know. 🙂
Thanks,
Geoff
