It would be great to have more manual control over figure and table caption numbering - specifically, to be able to restart numbering and to add a prefix. Many journals allow the inclusion of supplementary materials but captions need to be marked as e.g. "Supplementary table X:" and the numbers need to restart from 1. Ideally it'd need to work for the bookdown::word_document2 format as journals often require submission as a .docx.

This has been asked as well by others on StackOverflow, but I didn't see any answers, so I'm assuming it'd be a feature request.
