Just some ideas!
Maybe you could make so that one person can send another person the vocabulary which he uses because most time, when there are two students from the same class they usually learn the same words, so if the first student sends the other students words, the other student doesn’t have to tip them all because that takes time. You could also make groups so the teacher could send the students words.
That were just some ideas but I would be really happy if some of them are possible.
Thank you
