Polylang action when untranslated page

Hi,

I have a two-languages website using Polylang. I have some pages i don’t need to translate, and so, in English or in Franch, i wan’t to show the same page. For now, the only way i have to do that is to creat anyway another page for the other language. If i create a page with no translation, when user swap language, it swap the website language and show the home page.

I would like to know if it’s possible to make a dual language page with polylang, or at least, showing the same page if there is no translation for the page ?
And so, if user swap the website language when there is no translation for this page, it swap to the other language website, but keep the untrnaslated page anyway because no other language exists for this page ?

Is there a way to do that ?
I don’t if i’m clear 🙂
