Hey Emmanuel. That’s a solid request, but unfortunately not doable in the current code. The only way to do it would be to have the event run from 7-12, and detail in the description field how “show one = 7-10, show two = 10-12.” That being said we are looking into custom recurrence patterns like this for the plugin’s 2.1 lifecycle and it’d probably carry some weight if you mentioned this in our Feature Requests thread here: https://theeventscalendar.com/support/forums/topic/events-calendar-pro-feature-requests/.
Apologies that I couldn’t offer up more in the short-term. If you have other questions or if we can do anything else here, please let us know.
