Multipliers for each attribute | WordPress.org

Hello, good day, I am testing your plugin, I would like your help, my situation is as follows: I have a flower store and each arrangement that is sold is made up of a certain amount of flowers and a base (box), e.g. “arrangement in special box” contains 20 roses and 1 base, is it possible to affect the base inventory by 1 and the rose inventory by 20? I try but setting the multiplier to 20 deducts 20 bases and 20 roses, I don’t know how to configure it to affect each attribute separately.
