roxygen and a single help file for multiple data sets, deleting extra information

I am trying to create a help file that services multiple data sets that are all similar. However, roxygen generates a sequence of text that says something like "An object of class...", but it makes my document (of many data sets) look messy to me. Is there a way to delete this?

I tried to make a simplified example of the problem. This is using three data sets (data1, data2, data3). All three data sets have the same number of dimensions.

#' Example with multiple data sets
#'
#' The a description
#'
#' @format Simple format
#' @name multi_data
#' @keywords datasets
#'
"data1"

#' @rdname multi_data
"data2"

#' @rdname multi_data
"data3"

This is making the multi_data file look like:

You can add the line

#' @format NULL

before each of the @rdname lines if you don't want any format text to be generated.
