Different Sorting for main categories in different languages

Hi to alI fellow cs-cartians!

I had a question from a customer about the different sorting of the main categories when you use more than one language in the store.

His problem is that when he sorts the categories in Greek for example the same type of sorting is applied to the English language, which is not ok for him.

Is there something that I miss or this is the way it is?

Is there a possible workaround?
