[Feature Request]: `Add number to filename when saving` gives choice between `as a prefix`/`as a suffix`

Is there an existing issue for this?

What would your feature do ?

Say one want to cherry-pick images from SD outputs (automatically or simply without using the "save" button of the webUI) and gather them in a single folder. These images comes from different times/working sessions so from different folders (for example: outputs/<date>/<filename>) where filename is [number]-<your_pattern>.ext.

It means that once gathered in a single directory, images will be ordered by [number] and mixed... If one would be able to use [number] as a suffix (<your_pattern>-[number].ext), one would be able to have a nice "sorted by default" content without any hassle (I'm thinking [date] especially as a pattern).

Proposed workflow

1. Go to Settings > Saving images/grids
2. Checked by default: Add number to filename when saving
3. Select as a prefix (default) or as a suffix.
