Indesign numbering appendixes in a book

Question

I am working on different documents to create a Book. I have managed to fix all references, figures, numbering, etc But I do not know how to solve the following problem with appendixes:

I have 3 chapters: Chapter 1, 2 and 3. I have 2 Appendixes: Appendix A and B. The numbering works fine when I mix them all, but I have a problem with the list of my Figures. It is defined as: Figure ^H.^#: so Figures are named 1.1, 1.2... 2.1, 2.2... etc But when it comes to the appendix they are 4.1, 4.2... 5.1... instead of A.1, A.2... B.1... because, of course, the appendix is considered one more chapter.

How can I redefine "^H" so it is a letter and not a number in the appendixes? Of course this letter has to increase at every different chapter, such as the number does.

Answer 1

Considering nobody could suggest a better option, the best solution I could find is:

Modify the appendix style to: Appendix ^H instead of using Appendix ^1 with the specific list for appendixes. Then Layout - Numbering and Section Options change to style "A,B,C..." in every appendix document, and specify "start at A" in the first appendix.

It is not an ideal solution - not automatised, but it does the job.
