Inventory based on an attribute Plugin

I am looking for a plugin that does the following.

My product is cloth, it has “Color” attribute and “Pack” attribute.

Color has “Green”, “White”, “Yellow” etc. Pack has “Half Pack”, “Full Pack”. Half pack is 5 items, Full pack is 10 items.

The inventory is based on Color, for example. Green has 20 inventory, if people buy “Green” and “Half Pack”, the total inventory should be reduced to 15, then someone else buy “Green and “Full Pack”, the total inventory should be reduced to 5.

In the current WooCommerce, Green+Half Pack and Green+Full Pack are two variations, they have different inventory.
