Can I assign a page to a category

Can I assign a page to a category, so that this newly created page acts as the content hub for the category?

So if I was to create a category menu in the sidebar or header, when someone clicked on my category Dj Gear, then they would be taken to my content hub/page that has indexed content and internal linking to other child categories and individual posts?

I was able to do this in Thrive Themes before and now can not seem to find this optin on GP.

Thanks
