Hey David,
Thank you for posting and also choosing PRO! I’d love to help assist with this, but please note that theme/plugin support and customization requests extend beyond what we’re able to provide.
We don’t have a built-in setting which adds a button to add new events, but the best way to achieve what you need is by creating a custom template as outlined in our Themer’s Guide.
You could also add a button to your submit event form page under Events > Settings > Display > Advanced Template Settings.
If you need any more instruction or clarification, please feel free to respond with any questions you have. Thank you again for reaching out and enjoy the remainder of your day!
