Demand Show in Wrong Week Bucket because of Lead Time

sometimes user wants to see the real demand in correct week bucket, for example, the material is needed in week 20, But on Order Recommendation report, it shows demand is in week 18 because of lead time of 15 days.     if there is an option for user to create a saperate MRP scenario without considering Lead time, and second MRP scenario considering Lead time, that would be great.

Thanks
