Hello

I have extended the SpendAmountGetItemDiscount promotion data, with the following property:

    [ContentType(DisplayName = "Custom Spend for Discounted Selection", GUID = "32bba45a-080f-4261-8883-d8475f64603e")]
    public class CustomSpendForDiscountedSelectionPromotionData : SpendAmountGetItemDiscount
    {        
        [EditorDescriptor(EditorDescriptorType = typeof(CollectionEditorDescriptor))]
        [Display(Name = "Exclude these brands from discount...", Order = 10)]
        [PromotionRegion(PromotionRegionName.Discount)]
        public virtual IList Brands { get; set; }
    }

In the processor I wish to exclude the products that is associated with brands added in my custom property. Next I have created this processor:

    public class CustomSpendForDiscountedSelectionPromotionProcessor : GetItemDiscountProcessorBase
    {
        private readonly CollectionTargetEvaluator _targetEvaluator;
        private readonly LocalizationService _localizationService;
        private readonly FulfillmentEvaluator _fulfillmentEvaluator;
        private readonly Func _targetGetter;
        private readonly Func _discountGetter;

        public CustomSpendForDiscountedSelectionPromotionProcessor(CollectionTargetEvaluator targetEvaluator, LocalizationService localizationService, Func targetGetter, Func discountGetter, FulfillmentEvaluator fulfillmentEvaluator) : base(targetEvaluator, localizationService, targetGetter, discountGetter)
        {
            _targetEvaluator = targetEvaluator;
            _localizationService = localizationService;
            _targetGetter = targetGetter;
            _discountGetter = discountGetter;
            _fulfillmentEvaluator = fulfillmentEvaluator;
        }

        protected override PromotionItems GetPromotionItems(CustomSpendForDiscountedSelectionPromotionData promotionData)
        {
            throw new NotImplementedException();
        }

        protected override FulfillmentStatus GetFulfillmentStatus(CustomSpendForDiscountedSelectionPromotionData promotionData,
            PromotionProcessorContext context)
        {
            throw new NotImplementedException();
        }
    }

Using these two overrides is there any way to apply the logic stated above? 

After having tried a bunch of stuff I'm fearing I might have to inherit from EntryPromotionProcessorBase and write Evaluate from scratch, which seems overkill only to exclude some products from the discount...

Any ideas? Thanks in advance.
