Including the option to easily and flexibility maintain multiple product sales recommendation preference hierarchy (By content, by size, by price, by manufacturer up-sell, by marketing), might be beneficial.
Not having the option to visualize product recommendation hierarchy preference , user might only rely on voice recommendation.
Having the option to visualize product recommendation by quality, by ratings, user might potentially not rely on external or voice recommendations (e.g. internship or basic users).
