Ai model generation reuse

This is actually a frequently requested feature.  Please see this post and upvote if it matches what you would like to see: P: Maintaining a scene or character across different prompts.

I suspect you may want to look into other applications, for example midjourney (in which one can address character consistency with cref). 

I expect Firefly (or An Adobe-successor-application) will at some point include a similar feature, but at current it may simply not meet your needs. 

To the best of my knowledge, this is not possible currently.
Possibluy you could generate one image of a character and use that within the gen fill in PS as a style reference

and use a second image with the charater pose to constrain the output.
It's a bit of a long shot though.
