2aces2aces,
Thanks for getting in touch! Well, I have good news and bad news. First, the bad news: this isn’t possible in the current version of the plugin. 🙁 Secondly, the good news: this functionality is currently undergoing testing in preparation for being included in our next release! 😀 When this functionality is released, you’ll be able to customize the words (and slugs) that are used for Venues and Organizers.
While I can’t guarantee that this code will pass QA and be included in the next release, you should definitely keep an eye out for it when our next release launches next month. Thanks! 🙂
