Gross/Net Price in pricing procedure

Hi Guys:

            I have a requirement that there are several  condition types with tax in sales order, users want to get the value without tax separately, because they will be in different G/L accounts.

            Is there any standard routine in pricing procedure can cover this?

            For example:

                   Condition<Input>           with tax       tax rate   

            Gross condition type 1         110USD         10%         

            Gross condition type 2         140USD         10%         

                  Condition<Output>          without tax

            Net condition type 1                100USD

            Net condition type 2               127.27USD

            Thanks.
