Mapping Columns During Data Source Switch

There are a number of instances where we test cards using an excel/csv file. We then switch it over to odbc and use the "Switch cards to use new data set" feature to move them over. During the process we might change the columns names which DOMO does warn you that the column names do not match. It would be nice if we could map the new column names to the old ones during the process so we don't have to modify all of the cards that are affected by the new column names.
