Product Bundles, composite, bulk or…

Hello, I think I might have purchased the wrong plugin, as I don’t seem to be getting the functionality I was hoping for with “WPC Force Sells 6.0.3.” Could it be that I am using it incorrectly?
I hope you can help me with a challenge I am facing and can’t find a solution to.

The issue is with a product that has many variations and needs to be included in other products/sold together, while also reducing the inventory of the items being sold.
This particular product can only be purchased in 10ml bottles, and its variations are as follows:
Nicotine: 0mg, 3mg, 6mg, 9mg, 12mg, 15mg, 18mg.
Base: 50/50 and 70/30.

I choose to sell it in larger quantities and combine the above variations to create the product.
Size: 10ml, 30ml, 50ml, 100ml. (For example, when selling 100ml, the inventory should be reduced by 10x10ml bottles).

Currently, when I sell it, the product is set up as shown here:
testwoo.com/rosengren74/product/blaze-red/

When a customer purchases 50ml, 6mg, 50/50, with flavor, they receive “2x10ml 12mg + 2x10ml 0mg”, with the remaining 10ml representing the flavor.
However, the inventory is not properly reduced because the product “50ml, 6mg, 50/50” does not exist as a separate entity; it is created by combining different variations, as described above.

It is not essential for the customer to see the complete composition of the product; the key is to deduct the 10ml bottles from my inventory correctly. Can you suggest a solution to this problem?
Perhaps with a plugin like “WPC Force Sells,” but I haven’t been able to make it work either.
