Post/Page for starting list of archive

Hello,

On the website of my local football club that I have created I want to have a custom made archive page which shows a specific post/page on the screen. I will try to explain what I really want.

If you click on a specific team in the menu or categories shown you will go to a page (i believe it’s rendered by archive.php) where I want to have more info then only that list.

So if you go to https://www.brederodes.nl/category/senioren/zaterdag-senioren/zaterdag-4/
you’ll see the list of articles of that team. But on top of that page I would like to have team info (which can be stuffed and managed in a post or page). But if you go to another team for example “zaterdag-3”, it must shown the page/post of that team with the list of articles underneath.

Does anybody know how to do that? or is this impossible in WordPress?

Thanks in advance
