Please consider adding a `lock` (or flag) that prevents staff from billing time against a task...
Ideally the lock would be triggered by the task status - i.e., they could not book time if the status shows that the task has been completed (or perhaps has not actually been started yet).
Currently we append `***CLOSED***` to the task name and change the status to complete but on more occasions than we'd like, staff continue to use an inactive task.
