Use an updatable deck together

Hi every one.

I’m not a power user of Anki, but now i have an idea how to use it to make some good stuff for me and my colleges but i’m not sure about possabity of Anki to satisfied my order.

I wanna make a deck with our professional test which can be updated without loosing data of user who update it. For example:

  1. We have 25 question. I have shared the deck with everyone.
  2. Everybody gotten so results is this one.
  3. Now I have same deck but with 50 questions (add some stuff) and share it again.
  4. Everybody updated their decks and got 25 learned questions and 25 not learned questions.

I hope i’ve explained in good way and you understood me.

Thanks in advance to everyone!
