How to get a Seed # from one specific photo to replicate 4x times (not replicate all 4x photos from the original seed prompt)

How do I get a seed # from one specific photo (let's call it Photo A) to use as a seed for 4x new photos eg Photo Ai/Aii/Aiii/Aiiii? Currently if I use "copy prompt" on one photo that was generated as part of a 4x set of Photos eg Photo A/B/C/D, and select 4x photos as the new output, it creates variations of each of the 4x original photos eg. Aii/Bii/Cii/Dii, instead I want 4x variations of that one photo. Otherwise I'm getting variations of some janky renders rather than 4x fresh new ones.

Attached one example, this keeps happening with some worse examples too that I've deleted where all 4x are the exact same, this at least had a couple variations in it.
