Save generated figures as Figure_X.pdf instead of fig-label-X.pdf

[rgaiacs]

Some academic journals still requires that figures are provided as separate files. For example, Wiley's Guidelines for the Preparation of Figures says

File Naming Convention: to facilitate ease of review, name figure files only with the word “figure” and the appropriate number.

Will be great if Quarto had the option to follow the file naming convention that journals impose.

Minimal Working Example

title: "MWE"
keep-md: true

  docx:
    fig-format: pdf

## Results

```{r}
#| echo: false
#| label: fig-mew
#| fig-cap: Awesome figure.

plot(c(1, 2, 3), c(1, 2, 3))
```

The above file is render using quarto render figure-mwe.qmd:

processing file: figure-mwe.qmd

Since you are using knitr, you can define a function to pass to fig.process option.
The function takes a path and return a path.
In your case input would be "figure-mwe_files/figure-docx/fig-mew-1.pdf" and output would be "figure-mwe_files/figure-docx/figure-1.pdf".
