Hi Yofie,
Thank you for your feedback and for highlighting this issue.
We understand the difficulty of managing large datasets within the Multi Reference field in SP Page Builder’s Dynamic Content, especially without a search or sorting feature. Your request for a search function and alphabetical sorting is valid and would significantly improve usability.
I’ll forward this suggestion to our development team for review and consideration in a future update. We appreciate you taking the time to share this, and we’ll keep you updated on any progress regarding this feature.
Best regards,
