Changing CTL_MainWindow_Title From Outside A Jar

[ekartz]

I know you can create an org/netbeans/core/windows/view/ui/Bundle_{branding}.properties file inside an org-netbeans-core-windows_{branding}.jar file to set the CTL_MainWindow_Title property.  Is there a way to do this in a .properties file that sits outside the jar?  I need the value to be changeable after the build is complete and without updating any jar files.

Thanks
