Incremental suffix in exported file names

[dimailer]

Description of the feature or enhancement you'd like to see in HandBrake:

I'd like to be able to add automatic incremental file numbering suffix to exported file name in "Save As" field.
The number should automatically go up by 1 after each export.
User should be able to set a number of digit positions.

exported-file-01.mp4
exported-file-02.mp4
...

or

exported-file-000001.mp4
exported-file-000002.mp4
...

What version of HandBrake are you currently running (e.g., 1.3.0)?

1.3.1

What operating system and version are you running (e.g., Ubuntu 19.10, macOS 10.15 Catalina, Windows 10 1909)?

Windows 10 1909

If you batch scan and use format "{source}-{title}", title will technically increment similar to this.

Otherwise, you can't do this and you'll have to manage it with a tool outside HandBrake or with a "When Done" script

I don't have any plans to expand the auto-name functionality any further at this point.
There are far too many name formats that folks would like supported and it's really not a good use of time or particularly practical to try support them all so instead it's recommended to use 3rd party tools if the basics provided don't cut it.
