Assign Teams in the Workload Balancer

The Workload Balancer is great for assigning multiple tasks to users quickly. But doesn't work when we need to assign multiple people to a task or assign tasks to teams. I know I can select all the tasks and bulk edit the assignments section of the tasks, but would love the ability to add multiple people when assigning or replacing tasks from the Workload Balancer of a project, not just one person per assignment.
