New Price in Blanket Sales Agreement

Hi,

Right now we can see Discount % and Discount Amount fields only in the pricing tab of Blanket Sales Agreement screen. If values are entered in these 2 fields at line level, a modifier is created with Application Method as Percent and Amount respectively. Our requirement is to have "New Price" as the application method in the modifier line when created via BSA.

Question - Is there a way to do this without manually changing the application method for each modifier line?

Thanks
