It is well worth exploring the switches for the TOC field, particularly the \b and \t switches.

The \b switch restricts the headings included in the toc to the defined bookmark.

The \t switch allows a comma separated list of styles names and outline level.

I have documents with many toc in them which are managed quite well with appropriate use of the \t and \b switches. I've included a selection below.

Overall table of contents

{toc \b TOC_ALL \t "Heading 1,1,Heading 2,2,S Heading 1,1,P Heading 1,1,A Heading 1,1,A Heading 2,2,R Heading 1,1, R Heading 2,2,TOC Heading,2,TOF Heading,2,2, Title,1, ,TOC Heading, 1, TOF Heading,1" \h }

Module 1 TOC

{toc \b TOC_API1 \z \t "S Heading 1,1,S Heading 2,2,S Heading 3,3, S Heading 4,4, TOC Heading,1,TOF Heading,1, Title,1" \h }

TOC of a section within Module 1

{toc \b TOC_32s22 \z \t "S Heading 4,1,S Heading 5,2,S Heading 6,3, S Heading 7,4, TOC Heading,1,TOF Heading,1, Title,1" \h }
