"Translating" untitled posts containing only images with Polylang

Hello,

I maintain a portfolio site for a friend where the majority of the posts have no title and only images inside, so there’s nothing really to translate. I know I could create the other language versions one by one, but there are 100+ posts that need to be translated at this point, so I’m interested if there’s a way to somehow automate this.

Also for future posts, it would be very convenient to have all their contents appear in the editor in the default language when I add a translation. Is that doable?

Thanks,
