Hi aovivo,
Thanks for your post. We do have a custom recurring events option that allows you make events on a monthly or bimonthly schedules (for example on the first Thursday of every month or the 14th of every month). Would that work for you?
We are working on making our recurring events feature even more customizable, but at this time it is not possible to do a more random schedule. If you need to have recurring events that don’t follow a pattern, you will need to make individual events for each occurrence. In that case I recommend that you use a post-duplicating plugin so that you don’t need to recreate the information every time- just change the date.
I hope that workaround will work for you for now. We will continue to work on expanding the functionality of recurring events. If you’d like to stay updated on our progress, you can add your vote to the feature’s thread on our UserVoice page.
Best,
Leah
