Add a setting to share data between sections

[code-bunny]

For my new site I've made a header and a header with a full screen height call to action/welcome. Currently I need add the nav links on both or have the main app handle the nav/header.

Is there some setting I am missing where site_scoped can work on both the main_header and the cta_header?

site_scoped allows you to share the data of a component between different pages.
What you're asking for is to share data between 2 different components.
I think that'd be a great addition.

Aye. I think it would be confusing for customers. So if I provide 3 different footers and 2 different headers... why would the user need to know they have to update all the menus. And then they'll need to know they have to go to different pages to update the different site scoped menus. Of course this should be optional. Or maybe we can have some menu builder that we can reference in the editor.

In my footer I'll always want to have the terms and privacy policy links. But maybe on a landing page I want a minimal footer with just those links while on the main site I have a full fat footer. Also common on shopping sites where there is a minimal header and footer for the checkout pages.

I think this may be better served with blocks we can share between components. Or menu builders that can be referenced in blocks. Building up your menu's in a dedicated menu UI that can then be referenced in different blocks would seem the most logical way to go. It also means in the site.yml the initial menus are defined.
