Is it possible to export everything a bundle consists of, including any files from the content repo?

I've "actually" read the documentation this time afaik, I am able to export the description + actions of a bundle, but not the files from the content repo. Is this as intended?

How can I migrate packages with content from one management zone to another, or do I have to pack it twice?

Kind Regards,
