[Feature Request] Custom save file directory

[deusnovus]

Overview

Allow the user to maintain a save file folder externally, at a custom folder path of the user's choice.

Smaller details

Possibly a duplicate of #4638 , but I think the original post's request was rather unreasonable. However, it would be beneficial to provide the option to maintain a save file folder externally for all users, including those who have an existing cloud storage plan, like myself.

Nature of request

N/A

Why would this feature be useful?

I personally use 3 different emulators that allow external save folder paths, automatically sync every file in Dropbox and use them throughout all my computers. I have never experienced corruption issues from incomplete synchronizations, but just in case, I also manually maintain offline backups.

A problem exist.
Every savegame uses a ramdom Save Folder.
For example, same game in PC uses 0000000000000026 save folder but in Steam Deck uses 0000000000000003
You not get a working Cloud Sync with ramdom save folders.

I am only using Linux in all my machines and I haven't encountered any problems transferring my entire "bis" folder from one computer to another via Dropbox; saves work as intended, though it would have been nice to have some semblance of what these random folders are. (like using a game's titleID for a folder name)
