It's been at least 7 years since I had to add bookmarks to existing PDFs, so my info was probably a little out of date.

Hmmm... wonder if you could create a completed EPUB, generate a proper TOC, then pull the toc.ncx and get rid of all the xml cruft.

For example, Sigil formats the toc.ncx like:

Spoiler:

  <navMap>
    <navPoint id="navPoint-1" playOrder="1">
      <navLabel>
        <text>Part 1</text>
      </navLabel>
      <content src="Text/Section0001.xhtml#sigil_toc_id_1"/>
      <navPoint id="navPoint-2" playOrder="2">
        <navLabel>
          <text>Chapter 1</text>
        </navLabel>
        <content src="Text/Section0001.xhtml#sigil_toc_id_2"/>
      </navPoint>
    </navPoint>
    <navPoint id="navPoint-3" playOrder="3">
      <navLabel>
        <text>Part 2</text>
      </navLabel>
      <content src="Text/Section0001.xhtml#sigil_toc_id_3"/>
    </navPoint>
  </navMap>

Everything is already nested/indented in a certain way.

So you strip everything besides <text> and playOrder:

    playOrder="1"
        <text>Part 1</text>
      playOrder="2"
          <text>Chapter 1</text>
    playOrder="3"
        <text>Part 2</text>

Search and replace the Parts:

Search: ^\s+playOrder="(\d+)"\r\n[ ]{8}<text>(.+)</text>
Replace: 0 "\2" \1

0 "Part 1" 1
      playOrder="2"
          <text>Chapter 1</text>
0 "Part 2" 3

Key points being:

• Blue grabs the chronological numbering of all the headings.
• Red grabs how deep the levels are.
  
  • Note that Sigil's toc.ncx formats using 8 spaces for the first level (in PDF, the first level is considered "0").
• Green grabs the actual chapter titles.

Then you adjust the red part for "10 spaces" = next level:

Search: ^\s+playOrder="(\d+)"\r\n[ ]{10}<text>(.+)</text>
Replace: 1 "\2" \1

0 "Part 1" 1
1 "Chapter 1" 2
0 "Part 2" 3

then you would just have to go through and manually change the (blue) numbers to match the PDFs pages... but at least the bulk of the formatting would be completed.
