If a given amount of time is allotted in Workload Balancer is not used-up by the end of the week, it should be automatically re-allocated to the following week as a surplus.
If for some reason, such as a user adding hours late, this "surplus" would diminish accordingly.
We just feel like not having this means the automatic-ness of Workload Balancer's allocation abilities is a fascade because we still have to manually move those hours forward.
