Just open a new bus, put it at unity gain and make sure it's in post, not pre. Create an aux track to route it to your cue system. Then hold the option key and drag it one at a time across the channels. Then close your mix and highlight the session file and goto "get info" in the tool bar. Check stationary pad and you'll then have a template from then on. Note: In 7.4 don't double click on your session template because it will create a copy of the session. Just drag the session file over the Protools icon. It will then open as a template and ask if you want a new session or to edit the current template.
Hope that helps.
