Word count (in addition to Reading Time)

[kris-brown]

Description

Hello! Document listings support a reading-time field (which assumes a 200 word/min rate). Is it possible to have access to the estimated word count directly as something that could appear as a field in a listing? Or if there is some way of accessing the word count computed by https://github.com/andrewheiss/quarto-wordcount as a listing field, that would also work!
