In Atticus, you can only choose one scene break image to be used in your theme. This means that automated scene breaks will feature a consistent design throughout your book. However, if you wish to use multiple designs for scene breaks, you have the option to manually import other images to serve as scene breaks.
It's essential to note that while manually loading images for scene breaks offers flexibility in design, each additional image contributes to the overall file size of your eBook. As such, it's advisable to consider the impact on file size when incorporating multiple images for scene breaks to ensure optimal performance and compatibility with various eReader devices and platforms.
