Hey there, Cal! Thanks for getting in touch and checking out PRO–we hope it’s a fit for what you’re looking for. 🙂
Good question. Yes, once a recurring event series is created, you can either edit the series as a whole, or simple edit one instance in the series. I will point out that editing an instance will break it out of the series, but you do have the ability to edit the topic and speaker for sure.
Also, I do want to note that we offer a full refund on purchases within 30-days. That would give you plenty of time to try it out and see if PRO works for you. You may also find this tutorial on recurring events helpful as well.
Does this help answer your question? Please let me know.
Cheers!
Geoff
