Thanks!
I have tried a couple of approaches, and early signs point to a solution based on the \index{x|see{y}} approach. I've got some more trials to run, and I will provide an update.
p.s. reading LaTeX documentation reinforces my gratitude for R documentation, and in particular that we have access to an abundance of vignettes with real examples. The tidyverse is the gold-standard for this, but a lot of other packages are emulating that approach.
