Multi language training system

Hello All, I am writing to see if anyone has had experience of using opigno for courses in multiple languages. We are using the system at the moment and are successfully providing training courses in English. The aim I have is to copy these courses and translate them into another Language (Portuguese). While this is not a problem the issue I have is separating the 2 sets of courses so students who speak English only see the English course and those who speak Portuguese only see that version. I had thought about using training catalogues to separate the courses. Is they a way to hide training catalogues based on user language? If anyone has other ways of managing courses in multiple languages please let me know :) Thanks!
