Disabling duplicate warning

I use Anki to study multiple languages (currently 18), so I have many cards with the same front. So when I’m adding new cards, the background often turns pink and I get a duplicate warning. Is there a way to turn this off? If not, I really wish there were. I understand the purpose of it within one deck, but not across decks. It takes a lot of time to look at all the cards with the same front and make sure they’re for different languages than the one I’m currently working on.

To avoid duplicate warnings, you can simply use different note types for every language.
