We’ll call it 'Fabrikam Testimonials', and we’ll give it a unique design, starting with the background. It has the same name as the original master, Fabrikam Theme, but with a number 1 in front, meaning it is the first copy of the original. The new master gets inserted as number 2.
To keep many of the design details of the current master, I’ll right-click the master, and choose Duplicate Slide Master. Let’s switch to Slide Master view and create a new master. My solution? Create an additional slide master for that section. But after thinking about it, I’d really like this 'Testimonials' section to look different from the rest of the slides, with its own layouts. In this presentation, I have customized the slide master and various master layouts and applied those changes to the slides.
