I have a manufacturing type product that comes out with 0 stock despite having materials.

I would like it to come out like Kit-type manufacturing products that show availability according to its materials.

I have an e-commerce that has the restriction of not selling products with 0 stock, so I cannot sell these manufacturing products. The type of product I want to sell are on demand, so they are manufacturing type products.

Any way to make manufacturing type products appear in existence according to raw materials? (like the Kits)
