I think this could be a pretty fun little addition, though I'm not sure how difficult it'd be to add. Essentially, when you create a lion in the wardrobe, they'd get assigned a number like a cub when it's born. Obviously this number is temporary so if you try to use an expired number you'd just get the invalid lioness error. But once they get their number, they can be imported into the scrying stone so you can view their outcomes. I think this could also be very beneficial when designing your kings, for example, to see like if this marking or that marking looks better on potential cubs. Maybe to save space there is a limit to how many "active" numbers you can have at one time, and the number only ties to the design that you saved that number at. So if you save a lion and create their number, then if you try to change another marking you have generate a new number.

If anyone has any additional suggestions i'd be happy to hear them! This is just a silly though I had before bed last night lol.
