Change language settings by project

I was wondering if there is a way to permanently change the language of a project. Some of my projects are in English, others are in German or in Dutch. When I change the language under Edit/Spelling and Grammar/Show Spelling and Grammar it changes back to English each time I close the project and re-open it. I would like to permanently change it to the other language so that it remembers the language when I re-open the project. (I use Scrivener 3.3.6 on a Mac). Thanks!

Mac OS claims to be able to auto-detect which language to use. You’ll find the setting in the System Settings → Keyboard → Text Input pane.

Yes, this seems to work. Thanks!
