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.
