Hey Jonathan,
at the moment you can use different static image backgrounds on different pages, yet one instance of a background slider. Same goes for the header slider – if you create one in the Theme Options panel, it will be displayed on every page you feature it on. If you need more variety in sliders, you can try installing any of the free or premium slider plugins and using their slider as an additional one.
Sincerely,
Andrii / Satori Studio
