Set itemize spacing in Quarto / RMarkdown PDF

Question

In LaTeX, it's easy to control the vertical spacing in an itemized list by using \setlength\itemsep{1em}:

\begin{itemize}
  \setlength\itemsep{1em}
  \item one
  \item two
  \item three
\end{itemize}

How would I control this in Quarto / RMarkdown? If I write an itemized list using just markdown, I can't control the spacing, e.g.:

1. one
2. two
3. three

Is there a way to set a "global" spacing setting for all itemized or bullet lists? That would work.

Otherwise, is there a way to set the vertical spacing for a markdown list?

Edit:

This is the header I'm using for a Quarto PDF document (I didn't realize the solutions might be sensitive to the document class):

---
format:
  pdf:
    documentclass: scrartcl
    papersize: letter
    pdf-engine: xelatex
    geometry:
      - margin=1in
      - heightrounded
    include-in-header:
      - preamble.tex

Answer 1

Assuming your are using the quarto pdf format, you could do something like this:

---
format: pdf
header-includes:
 - \apptocmd{\tightlist}{\setlength{\itemsep}{10pt}}{}{}
---

1. one
2. two
3. three
