Update dimension records with a set of values in given columns

Description

For a dimension, given a vector of column names, a vector of old values for those columns, another vector column names, and a vector of new values for those columns, it adds an update to the set of updates that modifies all the records that have the combination of old values in the first column vector with the new values in the second column vector.

Usage

update_selection_general(
  updates = NULL,
  dimension,
  columns_old = vector(),
  old_values = vector(),
  columns_new = vector(),
  new_values = vector()
)
