I don't know another way to copy columns, that is why it doen't appears in the tool
By the way, this are the first three files of the csv file:

Año,#premios,#clone,País,Idioma
1901,Nobel,Sully Prudhomme,Francia,Francés
1902,Nobel,Theodor Mommsen,Imperio alemán,Alemán
Use Bulk mode of the MDE REGEX mode
select the source column
value (.+?)
Destination Select a standard type custom field (you can't use a calc field)
value \1
