The Custom packs creator.

Hey, I have been trying to simulate the rarities from the OCG dueling packs in the Creator, but the fact that the Pack Creator is forcing me to use an algorithm makes it impossible to use the OCG rarities of cards can we be able to set the number of cards we want for a rarity instead of selecting a amount of cards we need to add. 

The OCG pack I want to simulate is "Ancient Guardians" where the pack is less diluted by filler, and you can easily play the archetypes in the pack without too much issue. There are no Secret rares in the original, and the rarities of cards are more understandable. 

Can we get the ability to change the amount of each card category?
