I want to create two presentations. The "blue" presentation is the main show. The yellow presentation consists of numerous custom shows that I use to explain various topics in the blue presentation.

As I go down the blue stack I want to be able to click a link to a custom show in the yellow presentation and when it is through I want it to return to the calling slide in the blue presentation. This is easy when everything is done in the same presentation.

I know how to make custom shows but I cant figure out how to call a custom show from a separate presentation and return to the original slide in the original presentation.

Any help would be appreciated.
