We have the supplement field |Engraver= you can use (it's been around for a few months, actually). It's just like adding the fields for |Arranger, or |Language= or |Translator= .
lovely!

There really were an extraordinary number. It extended into the 19th century too. The engraver for the first ed. of Satie's Gymnopedies was female.
