Thinking about this more, I have another related question. Is there a way to specify what a task needs independently of what a task is assigned? I could not see anything like that in Help -- but, of course, I may not have done the right search. In the tutorial, for example, assigning more glue to the task "paint bits" should have no effect on that task, since no glue is required.
Thanks again.
