Footnotes on rest markups

[Martin Brown]

Hello Lilypond residents,

I would really like to be able to add footnotes to markup text applied to rests (whole bars). I'm typesetting some Mahler and every second multi bars rest has a long German string which I'd like to add the translation to as a footnote (ideally with automatically incrementing footnote numbers).

So something like:

R2.*9^\markup { Fliessender, aber immer gemässigt \super 1 }\footnote \markup "" #'(0 . 0) \markup { \tiny "1. More fluent, but always moderate" }

From what I can see, this does not produce a footnote since a rest is not an event-based footnote and what I need is a time-based footnote perhaps. How would I encode that?

Thanks!
