In the Winter Waltz Event a Choco Hop Card Collection Book was introduced for the Event Choco Hop Cards. I really like this because my chests aren't full of Winter Waltz Choco Hop Cards and my collection is very neat and sorted. I don't know if something like this is already planned and the Winter Waltz Event was just the last test, but if not, I would really appreciate if the Winter Waltz Card Collection Book Code would be copied for the normal Choco Hop Cards.
