Percentage Discount

Hi, I just tried this plugins and setup a Smart Bundle product.

Is that possible to add percentage discount (in single product) and only cut the regular price? What i mean is, when I use 10% of discount (in bundled product tab), that discount is applied to each single product in that bundle. What I want is, i just want apply the discount only to regular total price. How?

My Setup:
Price format: Min-Max
Calculcated Bundle price: from Sale Price (tested with regular price but not what i want)
