I want to have an automation rule that will automatically take the top card of list A and put it in list B whenever list B has less than 3 cards in it. The problem is, whenever I try to make a rule like this, it insists on modifying/effecting only the card that is initially moved out of list B which starts the thing by making it have less than three. This seems like a simple thing that should be able to be done, please help.
