[Feature Request] configurable timestamps / names for snapshots

Would it be possible to make the name of the backups / snapshots configurable?
e.g. by using time codes like those defined here:
https://help.gnome.org/users/gthumb/stable/gthumb-date-formats.html.en

Using them one could create a string like this
"Data-Disk__%Y-%B-%d__%T_%A__Week-%V"

to create a name for backups like this:
Data-Disk__2024-May-25__12:15:00_Saturday__Week-21

(Yes I am aware, that this example might not be soo useful. It is just for illustration...)

I am asking for this, because I personally find the notation 20250525T1215 rather hard to read and not easy on the eyes. Having many of those in one directory I really have problems finding the one I'm looking for.

Thanks for considering and thanks for the great working script.

The issue names no files or tests. Start by locating where snapshot and backup names are generated and where configuration is parsed; compare the current timestamp notation with the requested configurable time-code pattern. Done means users can configure readable names while existing naming remains understood and usable.
