Is there is no possible way to study separate decks without combining all the material?
for example - I’ve finished the N4 deck, and want to start the N3 deck. There are still reviews left in my queue. If I start learning the N3 deck, will all the materials combined? is there a way I can remove old reviews? Do I have to reset the progress on my n4 deck completely to stop it from showing me N4 reviews when I am would like to study N3 only?
