One only entry per related posts

Not sure how to explain but I am used with other plugins to have only one entry content and the different flags per language, instead of different posts.

This is on the pages or post menu in the backoffice only having the default language as “entries” and that entry having their flags marked if translated or not. This makes it less confusing when handling the backoffice, as entries are grouped.

I’ve searched documentation and have not found a way of doing that with Polylang

thanks.
