I am working on migration schedules across the globe and everything is focused on the DayOne date (which is the day the customers come in and work in the new environment).

All my tasks are leading up to this point.
So Task1 is -60days prior to DayOne, Task2 is -32days prior to DayOne, Task3 is -30 days prior to DayOne, etc...

I basically have been creating a template/group of tasks for each region (North America, Asia Pacific, Latin America, Europe) and then I copy those tasks for each branch we are migrating just changing the name and the DayOne date.

How can I get all my tasks to shift based just on the DayOne date changing?
