Quantity Discounts for multiple categories

Hello:

Here is my situation...I have a store set up with 3 categories.

I need quantity discounts that span across Category One and Category Two. No discounts will apply to category 3.

I can set up a quantity discount for both Categories 1 and 2, however i would like to have the ability to purchase from both Categories 1 AND 2 to quality for the discount. By default, the quantity discounts only work if you buy products from the same category. I would like to apply this over 2 categories.

And then I attempted to set the store up like this

1. Quantity Discounts
     a.)Category 1
           i.) Products
     b.)Category 2
           i.) Products

2. No Quantity Discounts
    a.) Category 3
           i.) Products

Using this setup, The only way I can assign discounts to both Quantity and No Quantity Discount Categories is if the products are listed under this category, however I need to keep the products under their "subcategories"  because if I broke the products from under their "subcats" I would have no way of seperating "Category 1" and "Category 2" Products.

Any ideas? Let me know if I am not clear. Thanks!!

Hi Gavin,
     That looks like a very good suggestion, certainly worth testing!

Wow! Great Thank you!!

So this is what I have

Cat 1
    Cat1 Products

Cat2
    Cat2 Products

Cat3
    Cat 3 Products

Discount Category (Hidden) & Discounts Applied to this category
    Cat1 Products
    Cat2 Products

Seems to be working great! Thanks!!
