If you delimit the LaTeX commands you can put Markdown between them:

`\begin{center}`{=latex}Markdown *here*`\end{center}`{=latex}

or more realistically with raw blocks:

```{=latex}
\begin{center}
```

Some *Markdown* text goes here!

```{=latex}
\end{center}
```

Or you can use the attached filter (instructions inside!) and just type

:::center
Some *centered* text here
:::

which will allow your source to work for both HTML and LaTeX output.
