Admin menu structure

Question

Currently I'm working on a website and I want to separate the header- posts from the rest of the posts in de admin post menu. I added a menu-item which filters the category "header". But I want to exclude the header category from the post-list in the posts-menu.

<?php
add_action('admin_menu', 'events_menu');
function events_menu() {
    add_menu_page(
        'Header',
        'Header',
        'manage_options',
        'edit.php?category_name=header',
        '',
        '',
        4
    );
}
?>

The above code gives me a header menu-item with all the the category header posts. But I can't seem to figure out how to exclude the category header from the post-menu section.

Thanks!

Now that I think of it, why don't you just make your header posts a custom post type? It seem like that would give header posts their own space and keep them out of the standard posts menu. It might be easier to use on the front end as well
