SpriteSheet Assembly?

[Demitri]

I'm aware that GlueIt exists as a way to make spritesheets from files, but I'm wondering if a program exists that can do this and allow me to specify/change axis on a set of sprites (like the first set is the base sprites, the second set would be clothing and I would need to be able to freely modify the axis each of those sprites are at)

Or am I just better off using like Photoshop for that stuff?
