notation for the Celtic bow movement called a cut

[Tom Tobin]

Hello,
I'd like to request a feature for Lilypond, if it hasn't been requested already.
There is a musical expression in Irish, Scottish, and Cape Breton fiddling,
called a cut.  It is a quick flick of the fiddler's bow wrist, to cause the bow
to change direction three times.
It would be immensely helpful to add it to the typeset, much the way the turn ~
greatly abbreviates something complex.
It would be a bow marker, similar to the \downbow and \upbow.
It typically changes direction three times, but rarely 4 or 5.

I am trying to capture the bowing and ornaments of masters of Celtic music.
I want to be able to pass it on, to people who might be located remotely, or not
have access to a teacher.
Your freedom to express, and ability to instruct, with sheet music, is truly
impressive.
Thanks!
All my best,
Tom Tobin
