Deck Memory

I propose an idea that for each Planeswalker there can be a file where a list can be made of possible deck lists with notes. Not deck slots but simply notes. For instance with lets say the pw Calix- There could be a particular deck slot used only to build decks, but not battle with, that a player could fill with any given 10 cards for their deck, and then be able to title it and create notes for it in the seperate file folder, to look back on and see for example "This deck was great for the 2nd fight in Titanomachy". The notes, picture of 10 cards, and title could all be saved in the particular PW's file to look at whenever.
