Second or split inventory?

So I'd like to keep track of both my real-life paper cards and my Magic Online cards via Deckbox, but for obvious reasons I want to keep these in separate inventories, so I don't go building decks using cards from both versions together. Is this possible in Deckbox short of just opening a second account? If it's not possible, do you think it might be a useful feature (I know it would for me anyway!)
