Converting typst to LaTeX: can I tell pandoc to "pass through" certain commands?

[nullst]

I want to use pandoc to convert a typst document I wrote to LaTeX. Ideally I want the resulting LaTeX code to be "human-friendly", as in, I intend to keep working on the produced LaTeX document (mostly editing, but I may need to add substantial new content), discarding the typst source after the conversion as no longer relevant.

Is there a way to tell pandoc to treat certain typst commands as black boxes, just converting the syntax instead of substituting the definition? An example: I want the typst fragment

#theorem[
  Main theorem.
]

to be translated into

\begin{theorem}
  Main theorem.
\end{theorem}

Here the typst source uses the ctheorems package and defines the #theorem command using the functions exported from that package, but I explicitly don't want pandoc to look deep into what "theorem" means and how it is defined (I'm not 100% sure that pandoc can actually do that), I want the tautological translation. Similarly, my typst code uses many math commands like Dbcoh that I would like to be translated just into \Dbcoh regardless of what the definition is.

Judging by what I understand the pandoc philosophy to be, this is probably not possible, but maybe there is a way?

P.S. To be honest, I have already solved my current problem by writing a python script that performs a bunch of regular expression substitutions to convert my typst code to, like, 98% correct LaTeX code and manually fixed all remaining issues, but this only worked because I treat typst purely as a level of syntax sugar on top of LaTeX and adhere to the same writing style. I would like a more robust solution.

I can't think of any way to achieve that with pandoc -- sorry.
