Is there a method for defining the PATH to the Property Templates folder using a system variable like %SW_TEMPLATES%?

We share files between physical plant locations and each of those locations has their own local server supporting SW.  So far, it looks like common Property Template files between locations need to be referenced in the very same path at any location.  (example:  R:\solidworks\templates)  Where "R:" represents a share from the local server.  Is there a way to define a client environment variable as part of the path to property template files on the local server?  (example: %SW_SERVER%\solidworks\templates)
