Concept language

Hey,
I ran into the following.

At the request of a customer I wanted to put a language as a concept so that the customer could fill this language without the language being found by google without it being completely filled.

What I did is the following, I then queried the language from the sitemap and also filtered the langhref from it using the pll_rel_hreflang_attributes filter.

But could this not be made easier since I now have to remove all filters if the customer wants to show the language.

Thanks for contributing ideas

Kind regards,
Joeri Abbo
