Good evening Carla and welcome to the Events Calendar forum!
Thank you for your interest in our products.
We’ll be glad to answer your questions.
Is it possible after setting a recurring event, to go into the individual events and add changes to the description and add unique links (ie. links to a Facebook event).
The answer is yes. You can absolutely do that.
Once the recurring events have been created initially, you can edit their individual occurrence’s content to your liking.
Let me know if that helps.
Have a great day!
Geoff B.
