Hi Elias,
That sounds like a cool project, but it’s not something the current Events Calendar PRO was built to do. You could use a post-duplication plugin to just recreate the same post, and then change the time to be different but within the same day. You might also be able to achieve your needs with some customization, but that would be outside our scope to support. We’d be happy to recommend some developers who could work with you.
We are working on making more flexible Recurring Events so that perhaps you could multiple in one day. You can add your votes to the UserVoice thread for this feature. That way you can stay updated on our progress. You can also add your votes to the thread for events with multiple venues. If we get enough votes, we may consider adding this feature as well.
Best,
Leah
