Is there a way to add premade hair or outfits to the base sprite?

You must learn character customization on your game engine. I like composition method. Each body part as a gameobject, animate it on Unity animator, and in runtime just swap the sprite.
Manual method you must do frame-by-frame animation on sprite editor (Aseprite/Pixel Studio/Photoshop) which slower to make and bad in some conditions
