I'd like to rename one of my saves in order to better understand what missions I had just completed and how far along in the story I was at that save's time. However, I can't find anyway to either rewrite the name, edit the name, or simply overwrite with a new name.
I've tried using Load Save and Save, and neither provide the option to rename and older save.
How can I rename older saves? How do I rename any saved game?
