Quantity Discounts Based On Category

I have a category, for example, 7x5 frames, and in that category is maybe 50 products, each a different color/style. I need the quantity discounts to apply no matter which product in that category is chosen, for example, 5+ is $10 each, 10+ is $8 each, 50+ is $5 each. How can I make this happen?



Right now, in version 3, it happens in promotions. There was some custom code added/written to make it work. It is my understanding that we should be able to do this natively now? Or with an add on?



Any help you can offer would be greatly appreciated.

Unfortunately there is no way to do it. Additional code modifications are required.



As alternative, you can try use Export/Import feature to import qty discounts for the required products
