AX 2012 Fiscal Calendar Setup Question for 5 4 4 5 calendar

When I create a fiscal calendar in I can’t see how to get a 5 4 4 calendar. I can create a fiscal calendar for 12 periods with the starting date that I need.

The problem is that the calendars created are 30 days each from the date I entered and and not 5 4 4 calendars that I need.

  1. Is there a way to create a 5 4 4 calendar and if so how?

  2. If there isn’t a way, is there a way to manually enter a calendar or adjust the one that the wizard created?

Thanks
