Manage User Allocation / Hours in the "Unassigned Work" Section of the Workload Balancer

[#1]

We'd like to have the option to apply contouring (i.e. edit the distribution of the allocated hours per day/week/month) to tasks & issues in the "Unassigned Work" section of WLB.

The UI would be the same as that in the Assigned Work section.

A task's resource needs fluctuate during the span of the task and it is often known before a user is assigned but can't be captured via the Workload Balancer UI at the moment. This would make resource planning easier and more real-life.
