I have several subdecks (1 per chapter) underneath one larger deck(for the book) that I am adding vocabulary too. The thing is that the book frequently repeats words in vocabulary lists and I don't always remember whether I have already added a word. Is there a way that I can identify a duplicate card before/after it is created? And I would want to see if it is a duplicate with any cards in the current deck(for this chapter) as well as any in the parent deck (for the book).
