I am citing three volumes of the GCS (Die griechischen christlichen Schriftsteller). Two of them have the same editors, so the date is showing in the short title. How can I suppress this date?

(The workaround I am currently thinking about is to misspell an editor name (which will remove the date on volumes 2 and 3) with Früchtell, and then search the misspelled name and replace with the correct name [Früchtel] right before I submit.)
