iPhone - Keyboard language changes automatically for a specific contact

Hi,

I'm writing to discuss a currently non existing feature -- automatic keyboard language change for a particular contact when I use iPhone keyboard. We live in international communities more and more every day and I find it very difficult to constantly manually change keyboard language writing to people (be it text messages, Whatsapp and similar apps, emails etc.). This causes my dictionaries to create bizzare words (because it starts as one language, while I want to write in another), and before I realize it, I have to delete everything, switch the language and write things again. It takes time and with talking to people constantly it grows to be a bigger issue than one might think.

The best option would be to assign a primary and secondary language to a contact or base the language on the previous messages if they exist.

I tried to find a workaround but didn't manage to. Anyone know about this feature being worked at maybe? (I found a post from 2014 here on apple forum when one of the admins claimed it was being worked at, but 10 years later, no feature). Or does anyone know the workaround?
