Multi-Cell Pattern Shift

[kelbellene]

I have an employee who types out a weekly task list which just shifts a day every week. She is hoping to be able to "roll" the list to the next week which would bump Friday's tasks to Monday and fill in the rest. Is this possible in Excel? It would be just as good if she could type in Monday's tasks and it would auto-fill the tasks for the rest of the week in the correct order.

More of a visual explanation:

Week #1: a b c d e

Week #2: e a b c d

Week #3: d e a b c
