Copying a section/element to another page?

I’m wondering if it is possible to copy a section/element to another page, without relying on templates.

Don’t get me wrong, templates are great, but when you import them into another page, you can no longer singularly edit them; they are the perfect solution when you need the same exact element across multiple places on your site.

But when you just need to copy the general layout of a section you built on another page, and retain the ability to edit it after the import (changing the images, the texts, modifying a bit the settings), you are prevented to do these small adjustments.

Is there a way to copy a section from a page to another? Or to import a template into a page and then convert it into a “standard” element so that you can modify it?
