Suppress footnote auto numbering?

[James Gifford—NitroPress]

Is there any relatively simple or straightforward way to suppress footnote numbering — in simplest terms, make it use one character (*) for every footnote? For print, the "restart numbering every page" setting comes close, but for EPUB/Kindle, in which those "page" things don't exist, allowing footnotes to have continuous numbering either results in vast character strings (*********, etc.) or numbers that quickly ascend to two if not three digits. All normal layout and style issues aside, I'd like to be able to export a document with a simple, un-numbered ("always 1") link for each footnote.

I'm not even sure post-processing with a script would work here; I've tinkered with editing the EPUB export and it quickly gets very messy. Forcing ID to be stupid about this would be nice...

AFAIR, there is no such thing.

Just to throw it into the bitstream in case anyone finds it useful, I use numbered footnotes when there are only a few, which keeps the formatting simple although I think it's confusing to run into "footnote 5" when it's the only one in the chapter; it triggers a "wait, what did I miss?" sort of response.

My "real" fix workaround is to use asterisk-only footnotes (the first numbering option), then on export to EPUB — at least, on hard proofs and final versions — extract the XHTML content file and use a text editor to strip all multiple-asterisk strings to a single asterisk. Replace file in EPUB, convert to Kindle (if you're going that way). This works best with the "footnote following paragraph" export mode and a distinctive, unobtrusive style for each footnote.

An ID feature would make this so much easier, though...
