   I think it would be nice to retain metrics/columns with matching column names since a lot of times users would want to fix a broken chart or iterate on an existing one by replacing the datasource with a newer (and slightly updated) dataset.
   
   I know this requirement exists because as a former Data Scientist, I've done similar operation in Tableau a lot.
