As I am Italian, it would also be very useful to be able to set the output language to a language of my choice. This is useful in the case of a complex workflow such as “Deep Research,” which only produces output in English because all the prompts are in English. To make it work, I have to translate everything into Italian. It would be very helpful to be able to set an option that automatically adds something like “Please note! **ALL** output must be in language **[Italian]**” would be very helpful!
