unformatted entry a la Endnote?

Pardon this question from an Endnote refugee... I'm sure that this has been discussed before, but I can't find it in the forums.

Endnote lets one enter unformatted citations throughout a document (whether Word or LaTeX), like so: {Feynman, 2000 #345} . Once writing is complete, then scans the document and converts the unformatted citations in place to formatted ones (per whatever style is chosen), and appends a bibliography.

Does Zotero support such unformatted citation entry? The Word plugin has options for only Fields and Bookmarks, and neither one seems to be the ticket.
