Creo View custom commands distribute via server?

I would like to create some custom commands in Creo View, to open web pages and capture Annotation sets. I understand I can do this with admin_prefs or shared_prefs, but we have a complex IT arcitecture with users spread across 3 domains but all using one Windchill site, so to distribute via admin_prefs or shared_prefs means co-ordinating group policies across all domains and all IT departments. So is there a way I can distribute the gui_prefs file via Windchill?
