Different discounts for composite items

In a component i have 2 products. Problem is that i can define a new price only as:

1. new fixed price for both products! (each product is for different price so i dont want to set same discounted price) o
2. percentage discount (90% for example) Its better, but the result is not rounded and it does not looks good (i dont want to change settings of rounding in whole Woocomerce, because it has other impacts…)
3. I miss a option for static discount for example -10$

So is there any way, how to have rounded result in case of option 2?

Or is possible to set fixed discount – like described in point 3?

Or is it possible to sed new price per product separately?
