Data package - Auto detect data structure and include under @format

Say I'm documenting a data set as part of an R data package:

#' Data Set 
#' This is a description of my data
#' @format This data set contains 40 rows and 6 columns.

Is there a way to detect a summary of the data structure upon build rather than hard-coding the structure (i.e. "This data set contains...")?

I don't think it exists yet? There was an issue about it in usethis issue tracker, that was closed with the hint to open an issue in roxygen2 instead if there was still interest.
