IA to same person in different situation?

I expect @CMass got the correct meaning but what do you even mean by »put … in different situations« exactly? 

One could cut a person from an image and put it into other images either as an obvious collage or try to more intricately integrate it (with regard to color, lighting, …) or expect to change perspective, posture, …

Character Consistency seems to have been an issue for all AI image generators for a while, but apparently several of them can now maintain it with good results, so you may want to look into the alternatives if Firefly does not meet your needs at current. 

Hey @Maleca! 

Welcome to the community! It sounds like you're looking to maintain a consistent character between generations. While Photoshop doesn't currently have a feature for that, I’ve moved your post to the Ideas section for future consideration by the team.
