Allow task due date to use business days

We have several workflows which generate tasks as part of a service item request. The problem with this is that if a task is created on a Friday late, but it’s due in 3 days this really only gives that team part of a working day (if no holiday on Monday) before the task goes into overdue. Being able to have task due dates be set via business days instead of calendar days would allow for a more accurate portrayal of timeliness of task completion.
