Hello I recently purchased a Kobo Aura H2O. I was wondering if there was a way that I could add a collection within a collection...i.e. separate the books on my device by genre and then by author. I have read the instructions on the kobo website (https://www.kobo.com/help/en-US/article/1959/using-collections-on-your-kobo-tablet) but am still unable to move my personal collections between: From inside one collection to another. Can someone provide me with detailed instructions on how to accomplish this on an Kobo Aura H2O ereader? Thank you!
