How do I create a powerpoint presentation with multiple slide designs in one presentation?
use the menu bar each time menubar -> Insert-> New SLide …Now choose your layout from the pop up it shows similarily if you have the slide menubar -> Format -> SlideLayout and you can change the slide layout in case you want to apply some design to it ..read colour scheme…specifically to one slide only then menubar ->Format ->Slide Colour Scheme and press Apply instead of Apply to All
