Setting up global setting for the EPM-Addin?

I know you can make changes to the EPMXLClientPreference.XML file that change settings in the EPM-Addin.  I would like to know how this can be setup to be global settings for all users that log into BPC EMP client.  We are using Cirtix and the PDF here hints at this being possible but the direction are not clear on how to impliment it. Basically I want to be able to change the setting in the XML file and have them be global for all users logging in to the system.  We are on BPC 10 using EMP client 13 patch level 1.
