Five Day Cycle

Ok, here the steps.
From the calendar: If you have at least a full cycle configured with its periods, tap on Cycle , and now select those 5 days in the calendar , in order.
Now, tap on automatic copy, and Ok. (you may want to change the start/end dates).
This will automatically fill your whole term with this cycle.
If something is wrong the configuration, tap on Undo Copy.

All good. Thanks so much for the excellent customer service experience. I'll be giving 3.0 a five star review in the App Store today. Cheers.
