`include` shortcode, but for .ipynb files?

[cscheid]

There are a number of problems in Quarto for which our standard answer is "use include shortcodes". Unfortunately, those only work with .qmd files.

One particularly unfortunate consequence of this is that authors who only use .ipynb files are forced into a workflow that might be awkward for them. Specifically, textbooks that are authored entirely from .ipynb files have a rigid structure in a way that is not the case for .qmd files.

This feature would be helpful. Ideally I would like to have a single tex file which contains all the latex macros I want to use and just use a shortcode to include it in the beginning.

I include them separately in the beginning of each notebook as follows

::: {.hidden}
$$
\newcommand{\dd}{\mathrm{d}}
$$
:::

Which works when generating html, but breaks for pdf. Do you have a work around?
