Hi, I'm not IJ but I did some experimentation and I think I've figured it out - it seems the card.copy and card.paste commands let you copy multiple widgets at once.
So you'd do like this:
card.paste[A.copy[A.widgets.X,A.widgets.Y,A.widgets.Z]]
(As a side note, if you're referring to a card in a script you can just use the card's name, you don't need the deck.cards in front of it)
Let me know if this works for you!
