How to Combine PowerPoints
When making a presentation, you don't need to create slides from scratch. You can insert slides from other sources to save some time.
You can create a presentation from an outline, saved as a Word document.
A slide is inserted for every top level in the outline automatically.
If you have slides in an existing presentation that you want to add, PowerPoint allows you to import them directly into an open presentation.
A file browser window opens, where you can browse for the PowerPoint presentation that contains the slides you want to use.
The Reuse Slides pane opens, displaying the slides in the selected presentation.
The selected slide is added to the presentation. Notice that the content of the slide is copied over, but the theme—including the colors, background, and font—is not.
