Not sure what you mean by hotspots, since all sprites will have their own, and you can only set that in the editor.
I take it your talking about moving a bunch of sprites as if they were one image?
If so you can use image points, but that has one of the drawbacks of a hotspot, you cant change it during runtime.
But with image points you can have as many as you like, and use one image as the base for the group.
