Can someone please point me in the right direction; I'm sure this particular situation must have been dealt with before.
I use multilevel numbering in my document associated with styles, i.e. 1.0 Heading 1; 1.1 Heading 2; 1.1.1 Heading 3; etc.
I have also created a style for autonumbering appendix headings, e.g. APPENDIX 1 etc. For this purpose I have created a style 'Appendix Head'. The prefix 'APPENDIX' is part of the the style, in other words, I select an empty paragraph and apply the style 'Appendix Head', and the result is e.g. APPENDIX 1 for the first appendix. Is this a standard method for numbering appendices or should one rather use the 'SEQ' field for this purpose?
I now would like to autonumber the headings in the appendices to look similar (in format) to the regular document headings, although they need to be independently numbered of the document heading numbers, and include the prefix 'A-#' where 'A' denotes Appendix, and '#' denotes the appendix autonumber, for example Heading 1 of Appendix 1 should be 'A1-1', Heading 2 of Appendix 1 should be 'A1-1.1', etc. Likewise, Heading 1 of Appendix 2 should be 'A2-1', Heading 2 of Appendix 2 should be 'A2-1.1, etc.
To summarise, the document structure should look something like:
DOCUMENT
1.0 Heading 1
1.1 Heading 2
1.1.1 Heading 3
2.0 Heading 1
2.1 Heading 2
2.1.1 Heading 3
etc
APPENDIX 1
A1-1 Heading 1
A1-1.1 Heading 2
A1-1.1.1 Heading 3
etc
APPENDIX 2
A2-1 Heading 1
A2-1.1 Heading 2
A2-1.1.1 Heading 3
etc
