Item with two volumes published in two different locations

Trying to enter this into Zotero:

DE BRIE, G. A., ed. Bibliographia Philosophica, I934-45. I. Bibliographia Historiae Philosophiae, Brussels, I950. II. Bibliographia Philosophiae, Antwerp, I954.

Am I correct in assuming that there's no way to enter this into Zotero as a single item, which includes all this info (eg, with some fancy syntax in the extra field)? That is, in such a way that it could display in a single item in some proximate style?

Thanks.

    Personally, I would recommend just citing this as two items. That will be easier for readers to understand.

    It is not currently possible to cite a collapsed item like this in CSL
