AGLC3 Rule 5.4.1 (about Pinpoint references for books):
Mentions adhering to rules 1.1.5 – 1.1.6. If a book has pages numbers, pinpoint references should be to page numbers… (or to paragraphs, or to a combination where applicable)…
My reading of this is that you can follow the given, alphanumeric appendix page numbering, including a page range like B-5-B-6.
