Public Sub AutomaticLength ()
Use the CustomLength(Single) method to specify that the first segment of the callout line retain the fixed length returned by the Length property whenever the callout is moved. Applies only to callouts whose lines consist of more than one segment (types msoCalloutThree and msoCalloutFour).
Applying this method sets the AutoLength property to True.
