Cost and date aggregation in CN41 and CN41N

Hi Friends,

We are having an issue with transaction CN41 and CN41N, where the costs and dates are aggregated and not matching with the dates (basic start and basic finish) in CJ20N. I know that we can go to transaction OPSL and switch the configuration for the dates and cost NOT to aggregate so that the dates for CN41 and CN41N can match with CJ20N. But my requirement is that I want only the cost to aggregate, but the date should not aggregate. Is there a way to do this in SAP?
