Possible to filter out private tags from previous and next posts?

Dear Ghost community,

I am using private tags (#de) to make our blog multilingual. Everything works perfectly so far, we can navigate to German posts and English posts.
At the very bottom there are 3 additional posts being displayed with the same primary tag and same author.

Is it possible to filter out the #de tags when there is no /de in the url and only display the posts with #de when there is /de in the url?

Something like this ?

{{if url contains /de}}
{{#next_post}}
{{> “post-card” filter=“tags:hash-de”}}
{{/next_post}}
{{end if}}
{{else}}
{{#next_post}}
{{> “post-card” filter=doesn’t contain “tags:hash-de”}}
{{/next_post}}
{{end if}}

@mangoldn This requires the implementation of dynamic routing for the next/previous post helper, which is not available (yet?). Please vote for it below:

Thank you @Stromfeldt I see I’m not the only one having this issue!
I was hoping that with some handelbars and Json syntax we could bypass this issue. Although I’m sure with expert development knowledge one can fix this problem…
