I have a large (300+ pages) document and after a bit of trial and error I
have modified Heading Style 6 and 7 to use for appendicies style 1 & 2 Not
much of the original style left, but still allows me to include the chapter
number for things like labelling figures and tables. I have customised the
outline numbering for style 6, the level is still 6, but the number format is
now A1 (I added the A in front of the 1).

My headings are therefore along the lines of:
A1 First Appendix (style 6)
A1.1 First bit (style 7)
A1.2 Second bit (style 7)
A2 Second Appendix (style 6)
and so on.

Then for the appendix headers I have the page number (including chapter
number), I have then had to add the "A" bit in front to give Page numbers
A1-1, A1-2, A1-3 (in Appendix A1) and A2-1, A2-2, A2-3 (in Appendix 2) etc
etc. The "A" bit of course is not shown in grey as its not an updated field.

The problem comes when I create a Table of Contents..... Although if I
include up to style 6 it created the main table ok, the page numbers on the
right of the Table of Contents only show the 1-1, 1-2,1-3 etc bit, the "A"
has been omitted.

Any ideas? - I suspect this links right back to the outline numbering of the
style having to add the "A" manually. Any way to create a custom outline
numbering format? I can update all the Appendix TOC fields at the end by
manually adding the "A", but then I can only update the page numbers as any
changes to the whole TOC will remove the "A"'s again!!!!!

Please help
