How do I change the Start/End date on a Schedule Group?

The Start and End Dates of a Schedule Group are determined by the Start Date of the first Schedule Task within the group and the End Date of the last Schedule Task within the group. To alter the Start Date of a Schedule Group, you must edit the first Schedule Task's Start Date, and to alter the End Date of a Schedule Group, you must edit the End Date of the last Schedule Task within the group.
