Is it possible to generate multiple images of the same target using StyleGAN?

I have seen many examples of NVIDIA StyleGAN. They generate endless human faces, anime faces, cats, dogs. I wonder is it possible to generate multiple images of the same human, anime, cat or dog?

StyleGAN doesn't have any concept or representation of a specific subject (person, animal or what have you). It only has "styles" at different levels of scale (coarse, medium, fine). It also has noise inputs at each level. If you vary the styles you're probably going to get images that look like different people (different shapes of the face if you change coarse style, different skin color and hair if you change finer layers). If you keep the style inputs the same and let the noise inputs vary, you will technically get different images of what will probably look like the same subject, but they won't be different in any interesting way.

I think there are more recent versions of StyleGAN that allow you to change the pose of a face while keeping the identity more or less the same, but the original StyleGAN makes no such guarantees.
