Simply select that option from the drop-down and when everything is set, click "Save" to begin the process of loading the text file. Each line will be a single event and each event will be scheduled daily. Enter "[SKIP]" for any days that no event should be scheduled.

Insert a delay of 7 days to take the week off and continue where you left off later. Going on vacation? Insert a delay. But don't be a vegetable! Updates are not fully tested and you may have to just delete the old calendar and import the modified version if it does not work. Requires .NET 4.0 client profile
