As a clothing Retailer, my company does not maintain pricing at a variant level. We do not sell an Extra-Large shirt for more than a Small shirt of the same color. However, we often place different pricing on different colors of the same style if, for example, one color will not be extended into the next season and the others are. We would place a discount on the close-out color. We use Supplemental Hierarchies to either include or exclude items from Discounts. Unfortunately, when an item is added to a Supplemental Hierarchy at a Style/Color level the Supplemental Hierarchy automatically explodes that line out to the individual variants. This causes Supplemental Hierarchies to get very large. We currently have a number of them that are upwards of 100,000 lines, which become very difficult to maintain. Supplemental Hierarchies do not explode items that are at the Style only level, nor at the Category level. Please consider changing the behavior of Supplemental Hierarchies so that we can enter and maintain lines at the Style/Color level similar to the way Discounts can.
