product similarity

Awesome work guys, please i am in need of a customization that allows all vendors sell similar products with similar features i.e similar variation, attributes e.t.c. I use the single-seller multi vendor module, and i want the customization such that; if a vendor adds a product to its store that product would still possess similar variation, attribute, quantity e.t.c and the quantity of that product changes as customers order for them irrespective of the store where the product is ordered from, since i am the only seller of products on my site, thank you. I use the woocommerce marketplace plugin.
