since sync takes a lot of time when you have a huge collection of flashcards, i want to choose the decks that i sync since the one that i don’t want it to be sync is used only to find relevant cards and change them to the deck that i’m currently studing ( it is like a resource where i can find good flashcards and change em to my deck but i dont want it to be on my phone neither on ankiweb) is there anyway to do so?
