Zotero CSL item types
I was wondering if there was a way to differentiate between two items of the same document type (i.e. legal-case) in CSL. For instance, to have different reference output for cases from the International Court of Justice and the European Court of Justice (i.e. both would be under the document type of legal-case)? Is there an option such as a "keyword" or an "identifier" which could be used in CSL to differentiate between two items of the same category?
