Question Split sprites, UV and rotation

Hello everyone, I'm at a dead end, I need your help.
There is one big picture, in runtime I split it into Sprite sprites.Create.
When outputting a sprite, I set the material to it with my shader.
I want to make a SEPARATE uv rotation for each sprite. But when you rotate, other parts of the image are visible (because, as I understood, the UV is general, from the full picture, and not the cut piece).

How to make "Rotate" correctly and calculate "Center" exactly in the center of a separate sprite?
