Hi there! 🙂
Great question! It’s definitely possible to edit the details of single instances within a set of recurring events. Once you’ve created a recurring event, you’ll see all of the events within the specified range listed in the WordPress backend under Events–just hover over the event instance you’d like to edit and click “Edit Single” to edit the details for just that event.
I hope that helps–let us know if you should have any other questions! Thanks for getting in touch!
