in WordPress I created 2 versions of each page of my website.

For example :
I have the page “contact” in a summer version (let’s call it V1)
and the page “contact” in a winter version (let’s call it V2).
I would like to put a switcher button in the menu to be able to change from one version to the other exactly like the language switcher from Polylang for example.
So I need to be able to say to wordpress that V2 is the same page but in a different version of V1. And I need to be able to create a dynamic link in the menu…
The visitor should be able to switch from one another at any time.
I am not sure it’s very clear and I am so sorry about that.

I am searching for a plugin to help me as I am not able to code…
