You can multi-select components in a blueprint’s Components view, but when you drag them onto another component, only one becomes the child of that component. When dealing with many components, this requires an absurd amount of drag-and-dropping.

Hello, Thank you for your feedback. I have actually personally made a report for this a little while back. It is in our system and assigned to a developer to fix. Please let me know if there is anything else that is not behaving as expected. Cheers!
