Is it possible to insert PowerPoint Slides from one ppt-file into another ppt-file and update the linked slides with Novell Vibe?

We would like to create a "PowerPoint source file" and use the slides of this source file in various other PowerPoint presentations. It would be very comfortable if there is only one such source file. In this way one just needs to update one file and not all presentations. As far as I see this is only possible with Microsoft SharePoint but not with Novell Vibe. Is there any way to implement this in Novell Vibe?

Thank you!
