Transferring very large amounts of photos between iPhones and keep original names and order

Is there a way to copy huge batches of photos from one iphone to another iphone (that is already in use) and have them keep the same names and same order on both phones?

I want to copy thousands of photos from my boyfriend’s phone (iphone 11) to mine (iphone 14) and it gets very confusing when they have different names on my phone than on his phone. I am already using my phone too so I can’t use Quick Start to do it.

I’d appreciate any help.
