coupon Allow combine rule

[Carolharry]

Hi All,

When setting up a coupon we have option of Allow Combine. I thought that means more than one coupon can be applicable to the product.
I tested and looks like it's applicable for the whole basket.

We want to allow multiple coupons can be applied to the basket but only one coupon(best coupon) will be applied for a product per basket.

The difference in our requirement and the allow combine rule is

If product A has 10% and 5% coupons available
If product B has 5% coupon available

In AbleCommerce Checking Allow Combine for 10% coupon and 5% coupon will have the basket with
Product A --- Price
10%coupon---(-10% of price)
5%coupon---(-5% of price)

Product B---PriceB
5%coupon---(-5% of priceB)

What we what is , if the user enters 10% and 5% off coupons then
Product A---Price
10%coupon---(-10% price)
Product B----PriceB
5% coupon---(-5% of priceB)

(Product A coupon should have 10% applied bcz it's best of both coupons) and Product B should have 5% coupon applied.

How can we do this. Can anyone in AC dev please suggest workaround for this.

Appreciate it.

Thanks
Carol.

Just pointers for work around even if it's customizing code will be useful.
