... My search came up with references to a "PropertyLinkGlobal" flag. ...
You got it all wrong. If you find references to that, provide links to those threads so that people can advice you about what those threads are talking about, and how it is not related to your problem.
Simply put, you cannot cross a Body
barrier when referencing other geometrical shapes. So, just follow chrisb's advice and use a PartDesign ShapeBinder
or PartDesign SubShapeBinder
App::PropertyLinkGlobal is a property
of an object. Unless you intend to program in C++ or Python, you have no business with it. It is not a "flag" that you can turn on or anything similar.
