enhancement per_day:false per_time:file

I want to be able to set
"backup_per_time": "file"
"backup_per_day": false,

and have files save in proper heirachies, with stamped filenames, like this plugin used to do in ST2
https://github.com/joelpt/sublimetext-automatic-backups

backups/path/to/file/filename.date.ext
backups/path/to/file/filename-date.ext
etc.

Would this be implementable or problematic for the in app previewer ?

I much prefer having all files where they belong, and not in separate dated folders, despite the obvious limit issues.
