I manage an extranet for our partners. Each partner gets its own space for sharing documents between our companies. To help them do this, I need to modify the Default Space Content template to have buttons that will enable them to add child pages based on other templates I've created.

The best way to do this appears to be the Create From Template macro. However, it is not available to be used in Global Space Content template. In the macro dialogue, it does not display global page templates in the dropdown.
