title: How Can I Customize Number Sections RMarkdown?
body: <p>I've been working with R Markdown to generate Word document files. I'm using Bookdown as well. Automatic numbering works great so far, but it runs as 1, 1.1, and 1.1.1, but I want to customize the numbering to run like 1, 1.1, 1.1(a) or even with roman numerals.</p>
  <p>I'm certain this is possible, but I've been wracking my brain trying to figure out how. I thought that maybe a Pandoc filter would be useful, but I didn't know where to start. I thought this might help,</p>

  <p>but I was having some trouble understanding how I would modify that filter to work for what I need. Any help would be awesome.</p>
