As far as I know, the only way to "rename" a save is by making a new and identical save altogether under the new name and deleting the old one. However, this messes with other saves that have links to the renamed save since its save ID is also changed.
Could we get a feature to rename saves directly without changing the save ID? It's a quality of life improvement that I'd greatly appreciate.
... Or maybe I'm missing an existing feature. Is there already a way to do this?
