selecting a global variant for a page

I’d like to be able to select a specific global variant for a specific page directly from the editor.

Say I use a global variant for internationalization named “locale” with two values (“en” and “fr”)
Now I have a page “/fr/fromage-ou-dessert”, a French page

I’d like to select the French locale for this page so that I don’t have to do it programmatically and I can also view all the components displayed in French in the editor when I edit this page


I think it is similar to this issue: Is there a way to set a global variant on the page in Plasmic?
