Configurable default Attribute ConfigString

Right now, when you create an attribute in a template and assign it a Data Reference of PI Point, it defaults to a ConfigString of "\\%Server%\%Attribute%". %Server% has some known administrative headaches because what it populates as is dependent on the default server of the client tool.  But in our company we are constantly switching between environments and this causes mismatches. As recommended by OSI we have created an attribute in the root AF element called Server and gave it a string value of the name of our server.  Now when we create a new attribute we map a reference to that attribute instead of %Server%.  But if we forget to do that, then it goes back to %Server%.  We would like a way to configure (on a global basis) the default ConfigString for new template attributes.
