It would be great if the app could add an option to count the number of unique vendors for discount eligibility. Currently, when setting up discounts, it only counts unique collections, which can be limiting. For example, if a discount is applied to orders containing products from at least 2 unique vendors, this would enhance flexibility and usability. The current workaround of adding every vendor as a collection is not feasible for shops with many vendors, and relying on exclusions can be cumbersome. This feature would greatly improve the discount setup process.
