I have been using pandoc + LaTeX + Biblatex for several years now as my normal tool for scholarly writing, and I find the biblatex filter really excellent. For some reasons, the style of a journal requires  a particular biblatex style "mixture":

```

citestyle=ext-authoryear, bibstyle=ext-authortitle

```

For a similar use, see e.g. https://tex.stackexchange.com/questions/433643/customizing-biblatex-authoryear-labels-in-bibliography-and-format-of-editor.

Question: while I normally write, in my YAML header:

```

biblio-style: <required style>

```

I was not able to find a YAML instruction suitable for this particular need, i.e. two searate style for citation and for the final bibliography. Not a big issue, since I can edit the TeX file with s simple sed script, but I was just curious to know if it is possible to incorporate this instruction within a YAML header.

Many thanks for everything.
