Exclude the most expensive item in cart from discount campaigns

We want to create a discount campaign that applies a percentage discount (e.g., 10%) to all items in the cart except for the most expensive one. This is especially useful for collections like rugs or furniture, where a few items in the cart can vary greatly in price, and the merchant wants to preserve full price on the highest-value item.

Currently, Discounty does not support this type of rule. Although merchants can manually exclude specific products from a campaign, there is no dynamic option to automatically identify and exclude the highest-priced item in a customer's cart at checkout.

Implementing this feature would give merchants more flexibility in creating smart, revenue-conscious promotions. If you think this would be useful for your store too, please give it an upvote!
