When adding multiple citations, Vancouver-Superscript, or Vancouver styles do a great job to place a delimiter ";" or "," between two in-text cites. But only when they are being added AT ONCE.

However, when adding one by one, Zotero can't figure out that two in-text citations that come exactly after each other, are actually parts of one entity; in order to place the comma, or other delimiters between them. Whereas, in Endnote, the parser can understand that two separated citation fields that are exact neighbors "must" be merged into one field.

For example, adding citations one by one with Zotero creates this: 12346789 or 1122223333 (Zotero doesn't care about duplicated citations, because it doesn't "see" their neighborhood, and put them in separated fields) but those independent but neighbor entries would appear this way using Endnote: 1-4, 6-9 and 1-3

I want it to be like Endnote:
to Change 112222333334 into 1-4
or 1124667 into 1, 2, 4, 6, 7

Thank you very much :)
