Tldr: I want to have two copies of the same packaged deck. Or rather, I want both the updated version and the old version. They’re not identical, but importing the old one blocks importing cards of the other. How can I keep both?
My example: I have imported and studied a deck from Eyeguru BCSC. Now I want the “same deck” as updated by someone else: Blue’s Eyeguru BCSC. This new deck contains further info inside each card; but no new cards. I can import the set completely if I make a new profile. But if I import the set to my original profile, which contains the original cards, I get the deck containing only get few card: only those which I had completely deleted from the original Eyeguru set. “pre-excisting” cards are not imported. I explicitly do not want any updates to the cards. I want the old cards unchanged (I have made my own changed, I need to keep those). I want the second deck (Blue’s Eyeguru BCSC) to be imported, as if it were being imported to an empty Anki profile. Would that be possible?
