Unfortunately it is impossible and here is no perfect solution.
If you need to edit related “articles” on the same page in the backend you can try to use ACF repeater field https://www.advancedcustomfields.com/resources/repeater/ but it is not the best idea because it can be a problem to show all articles on fronend.
I think the best will be to create one additional custom post type “articles” and make relation with “magazine” using ACF post Object field https://www.advancedcustomfields.com/resources/post-object/ but it will not allows you to edit articles on the Magazine page in the backend.
