Previous and Next posts in same language

I’m using my ghost blog website in 3 differents languages. Every language has it’s own posts. But the problem that I have is that I want to show previous and next posts only with posts that have the same language

For example, this post is in spanish. I only want to show the previous and next posts with the same language (spanish)

This functionality would require dynamic routing for next/previous post helper, which you can vote for here:
