Importing PowerPoint slide into Storyline

Hi Krupa,

Thanks for reaching out! Applying a theme or slide master is done only after importing the slides.

• Storyline 360: Using Design Themes

Once you've imported the PowerPoint slides, select them, and go to the Design tab to choose which theme you'd like to apply. You can also right-click on the slide and choose the Apply Layout option to select your slide master. I hope this helps!
