Hi there,
I'm using Chicago, 18th ed., w/ classic variants. I use the "volume-title:" in the Extra field for certain multivolume works, and am wondering if there's a possible tweak (to the style sheet?) that might let it preserve the capitalization of this field as-is on output. An example:

volume-title: Deutsche Ideologie: Manuskripte und Drucke

will output "Und" in the title:

Marx, Karl, and Friedrich Engels. Deutsche Ideologie: Manuskripte Und Drucke. Edited by Ulrich Pagel, Gerald Hubmann, Christine Weckwerth. 2 vols. Abt. I, bd. 5 of Marx/Engels Gesamtausgabe. Berlin: De Gruyter, 2017.

Item language is set as "De," which preserves capitalization in the regular "Title" field but not in Extra>"volume-title:". Is there any easy fix here, without potentially breaking something else in the style sheet? If not, I think it will be possible to return to putting things in the proper Title field, but have been appreciating the use of the Extra field here.

Thanks very much.
