Full author list for first citation in a chapter [apa.csl]

Question

I'm writing my dissertation in R markdown. I am using bibtex, pandoc-citeproc, and apa.csl with bookdown. I have new_session: yes in my _bookdown.yml and compiling primarily to PDF (documentclass:book, classoption: oneside).

The system I have is correctly using the full author list in place of "et al." for the first time I cite a 3-6 author work. That said, my adviser wants the full author list for the first time I cite a work per chapter.

Is there an easy way to go about this?

Here is the apa.csl I'm using:

Turns out that a biblatex based solution is indeed very flexible as @moewe showed on TeX.SE. When one combines style=apa with citerest=chapter one gets the effect you are after. In a minimal R-markdown document:

---
output: 
  pdf_document:
    citation_package: biblatex
documentclass: book
bibliography: biblatex-examples.bib
biblio-style: apa
biblatexoptions:
  - citereset=chapter

Make sure that your TeX system includes the biber program.
