A possible workaround is to: 1) keep the ”Newspaper Article” footnote template formatted to generate the full reference with the “Using footnote format” setting; and 2) edit the “Newspaper Article” bibliography template to show just the newspaper name. However, listing only the newspaper name seems a bit odd so could you clarify by providing a bibliography example showing how multiple entries from the same newspaper should appear? And if you’re able, to attach your output style file.
