I'm new using Tabletop Simulator. When playing a card game, I see you can reset the deck from its context menu and it returns all of the cards to the deck. However, this doesn't seem to work every time. It seems to fail most often if cards are grouped together or stacked and there doesn't seem to be a way to reset the deck if it's exhausted (such as someone drawing the last card and trying to reset from the discard pile) since you have to reset from the main deck.

Is there a way to make reset work for all of the cards?
Is there a way to maintain two different sets of cards (such as a blue and red deck, or one with jokers and one without)?
