Multi-Language Authors automatically recognized in the blog posts

Hi dear HubSpotters!

Multi-language variants of the blog authors have been created and there are 2 language variants of the blog itself.

But it seems we would need to select the new EN author in each blog posts manually as it suggests here: Create blogs in multiple languages

But my question is, is it not possible that the blog system automatically recognizes the language of the blog + author?

Thank you and regards
