I would like to suggest a feature regarding dynamic rules. Currently, B2BKing provides BOGO (Buy X Get Y Free) as an option. However, there is no way right now to discount a product partially when you buy a certain amount.
For example, I want to implement Buy 2 Get 1 50% off with every 2nd product being discounted 50% off. In more generic terms, a Buy X Get Y at Discount option. This is a common feature in discount plugins, but not for B2B.
