[Feature Request] Card Override, ignore in deck calculations

[Barbazu]

Sometimes, when building Commander decks, you want to put a card in multiple custom subcategories. Such as Draw and Ramp. But you only want one of them to count against the 100, or in mana curve calculations and such.
But you still want the list to display them in multiple places, such as under visual spoilers because you want to track the role/utility of the card and how many in total cover it.
