Anchor generation doesn't work properly for multiple TOCs

[MikeTO]

It's difficult to generate anchors successfully for a book that uses chapter-level TOCs with different heading levels than the main TOC. For example, a book with a main TOC might include Heading 1, 2, and 3 while its chapters might have TOCs that include Heading 2, 3, and 4.

When you generate the main TOC, you'll get properly nested anchors for Heading 1, 2, and 3. You'll also get Heading 4 anchors because Publisher doesn't let you specify the heading levels to use before generation like ID does.

After you've deleted the Heading 4 anchors, you would generate the chapter TOCs and deselect Heading 1. Unfortunately, this will move the Heading 2 anchors out from under Heading 1 which will break the PDF bookmark hierarchy. And new Heading 4 anchors will be created but they won't be children of Heading 3.

If you refresh the main TOC the Heading 2 ones will become children of Heading 1 again but the Heading 4 anchors will still be strays. If you disable Export as PDF Bookmark for the Heading 4 anchors they'll just re-enable when you update the chapter-level TOCs.

I've attached a screen recording and test document to demonstrate the issue. The problem is that the user would want the main TOC to drive the PDF bookmarks, excluding Heading 4, but also want Heading 4 in the chapter-level TOCs to be linked to the right page.

One solution might be:

• Introduce a concept of a main TOC and set "Export as PDF bookmark" only for its headings. I'd just use the first TOC as the main because it's most likely to be the main.
• Headings unique to chapter-level TOCs would still generate anchors but would have "Export as PDF bookmark" disabled for headings not in the main TOC to not interfere with the PDF bookmarks
• Change the Update All TOCs feature to update the main TOC after any subsequent TOCs - this would presumably fix Preflight, too

For anybody encountering the issue, here's a workaround but you can't include Heading 4 in your chapter-level TOCs (or any heading level that isn't in the main TOC) because there's not workaround for that. For the example I've given above, edit the Heading 3 text style and change Next Level to Same Style. It's okay to base Heading 4 on Heading 3 but you don't want Heading 3 to be connected to Heading 4. Remove Heading 4 from the chapter-level TOCs. After you have your TOCs set up, each time you want to update your TOCs, update all TOCs (through the TOC panel or Preflight > Fix) first and then update the main TOC independently.

Apologies for the delay here @MikeTO!

Thanks for the file/recording provided - it's certainly appreciated. I believe I understand the issue being reported here and therefore I'm going to log this with our development team now, providing this post for further context.

I hope this helps
