Is it possible to have a PowerPoint showing up in another PowerPoint? I don't want it to be embedded in the main PowerPoint I need it to be a separate file? The linked PowerPoint should come up inside the main PowerPoint.

The scenario is like this: We have a main presentation showing the progress in a project, we have one slide for each month showing a 3d image that depicts the changes from previous month. For each month I would like to show the actual photographs from the project. I would like these photographs to be located in separate PowerPoints (one for each month).

Thanks,
Roger
