Thank you for your message, and I completely understand your disappointment.
I’m really sorry that the feature you were hoping for isn’t currently possible. I know how frustrating it can feel when a key requirement impacts your workflow, especially right after purchasing a license.
However, I want to assure you that your purchase is not “for nothing.” SP Page Builder is actively developed, and many users successfully build complex Joomla websites with it every day. While this specific feature isn’t available right now, our team continuously explores new possibilities based on user feedback — including yours.
