Can we get a "build your own language" version of the app?

as far as I can tell, it is a lot easier to create flashcards with this app as well as get the spaced repetition than with Anki for me, however all languages are not supported. Is it possible to be able to create a "build your own course" section where we can create our own flashcard decks in our own languages? I would love to use this app for my Persian learning but there is no way to build out my own course here.
