Is there Any Bulk Discount Plugin working with Multi Currency

Hi guys

I have now tested 4 bulk discount plugins based on product rules.
i need to calculate product discounts in % based on item counting rules.
example: if there is more then 2 items of product XY in the basket, calculate 10% on the product.

the problem is, with your multi currency tool, this works fine for the first currency, which is for me Euro. The second price in product is CHF (Swiss Francs).

As long as i select Euros, the discount is calculated correctly on the product price. But if i select the second currency, it is not working. It seems that the discount plugins all goes with the first price field for products and not for additional multi currency fields.

do you know any bulk discount plugin compatible with multi currency or you have any other solution?
