Is it possible to create a recurring task using the GroupWise 8 client such that the next due date depends on when the previous instance of the task is completed.

For example, I want a reminder to get a haircut every 4 weeks. If it's cut today, the next due date should be 4 weeks from today. If I let it slide a week, or get it cut early, the next due date should always be 4 weeks from the last completed date.

Since I don't know the exact dates it will be completed ahead of time, the scheduling must be dynamic based on when it was last completed.

For now, I've been moving the due date ahead manually each time the task is completed.
