How can iOS developers update App Store metadata without hassle?

When creating a new App Store version to update ASO keywords and metadata, I notice that elements like the app icon and other details are missing and I am looking for a way to copy the existing metadata from the previous version.

Also, is it possible to submit a new App Store version solely for ASO improvements without uploading a new build and still have the changes applied successfully.

You can update App Store metadata without new build using Store Connect
