How to set different price for different product

Hi,

I am using the Upsell Funnel function.
I set Recommended Products as [Selected products].
Then the Conditions of Product I set to [Include Products] and select my products in the input box.
By this way, I can show multiple products in the upsell page, but all the products are having the same amount of discount.

May I know is there anyway I can set different price for different product?
For example,
Product A discount $5; Product B discount $10; Product C discount 20%.
All product A, B, C can be displayed on upsell page.

Please advise.

Thanks.

Regards,
