Bundle Discount: Require Specific Products to Trigger Discount

Ability to create a discount that only applies when a customer adds a defined set of specific products together (e.g., Item X + Item Y + Item Z).

Discount should not trigger when buying multiples of the same product.

Should support fixed amount or percentage discounts (e.g., 10% off the bundle).

Flexible setup: merchants can define 2, 3, or more specific products as the required bundle.

This would allow merchants to create true bundle-style promotions where customers must purchase the exact items together to unlock the discount.
