Hello and welcome 🙂
It is not currently possible to have multiple venues attached to events. We have that feature mapped to be included in an upcoming release, but I don’t have a specific date when that will be available.
I’ve gone ahead and added this thread to the ticket which helps increase the attention paid by developers. Please stay tuned to our Release Notes and the plugin changelogs for more information. Thanks again and let me know if you’ve got any additional questions or comments. Cheers!
