Yup, I wrote it way back when. I've since improved it a bit, and I
need to upload these changes to the LSR (which Mike S. is quoting
above) when I get it all finalized. Ultimately, I'd like to see this
kind of support in the codebase. As a theory teacher, I have used
this function many many times. One of my long-term goals has been to
work on this project--to take this from a snippet, and make a viable
part of the program. The big issue to resolve (other than the best
way to parse the user input) is how this all would interact with
LilyPond's figured-bass capabilities.

You can do this no problem. Just write:
\markup \rN { fII 6 }
or
\markup \rN { fA 6 }
Possibly you're using an older version? (I know several versions are
out there,)
The version for which this certainly works is available here:

Three or more figures aren't a problem. I've got that
working--somewhere. As soon as I get this all together, I'll update
that snippet on the LSR.

Yes, the \rN command is simply an aid to creating a complex markup,
which is immensely tedious if you churn this sort of analysis out and
want the symbols to look like they do in the theory texts.

This brings up another struggling point. There are slight differences
in the appearances of the markups depending on whether you use them
inside or outside a Lyrics context. Possibly I'm splitting hairs
here, but I'd like to resolve this.
HTH,
David
