New Deck Feature: Printings allow only certain sets

First, the printing options should be allowed to be set for each individual deck

Second, it would be nice to have the ability to have an option (at the deck level) that would allow me to specify which sets a deck can use for printings of a card.  This would be very useful for pre-constructed decks, as well as decks that are intended to use cards from a specific era (like say mirrodin standard era, which would allow onslaugh block, mirrodin block, and 8th edition only).  If a card in the deck doesn't have a printing in the allowed sets, it would be marked as "Not Available" but would still allow you to select a custom printing.

Simply put, when entering pre-constructed decks (see https://deckbox.org/sets/2139044) it's tedious to select a custom printing for all 100 cards when neither the Last Main Printing or My Inventory options will select only cards from the Commander edition).
