Rescheduling Orders in Aggregate Buckets

We are implementing constrained supply plan with weekly buckets. In weekly buckets, when a planned order is created, it is created at the end of the bucket. But, when the order is released, it gets released with the 'Implement Date' as the start of the bucket. This is right as the supply thus created at the start of the bucket accounts for demands throughout the bucket and there are no shortages. However, when there is a reschedule recommendation and it is released, we noticed that the rescheduling happens to the end of the 'Reschedule To' week. This defeats the purpose
