Hi Ron,
Thanks for getting in touch! I’m stoked to see you’re giving PRO a look and I hope it’s a good fit for your client. 🙂
Good question. You can definitely create a custom recurring pattern that would following that same Wednesday and Saturday pattern and edit the details of each individual instance of the recurring series. The only hitch is that editing the event details actually removes an event from the series–that doesn’t have a huge impact, but will make the event appear as if it does not belong with the rest of the events in that series.
Does that help answer your question? Please let me know and I’d be happy to answer any other questions you might have about recurring events.
Cheers!
Geoff
