Skin contrast with Nanobanana 3

Hi,

I am using Nanobanana 3 to make superheroes.

The first prompt creates too much lack of detail around the eye; so it is hard to see where the eye ends and where the skin begins - I hope that makes sense.

I solve it by using the output as a reference image into prompt 2:

"Good. Can the skin be more detailed. Can the lighting show less contrast on the skin?"

I wonder if you could have a sort of CLIPBOARD APPEND so that any prompt I do in my work, Nanobanana will append that extra instruction or even know to do a follow up batch task of doing the seconf generation for me?

Thanks
