Make the <header> #brx header available in the builder

Hey dear Bricks team,

I know that when I add links to the navigation in the new Nav (nestable) element, they are automatically wrapped into a <li>.
But here I also have the opportunity to create a wrapper myself, add classes and then style it.

Could this also be implemented for the header and footer?
Then I would be able to Style the <header> + <footer> without Custom CSS and i could also add Classes in case I create multiple headers.

In addition, I don’t need to insert a section because I then only need one container.
(Without a section it looks strange in the builder and a section in the header is wrong)
