Hello everyone / Instrument-Name-Abbreviation on front of every system

[UCas]

** me **

First of all, hello everyone.
I use lilypond for a few years now and until today I found a solution
for most of my problems by myself or by asking @JANieuwenhuizen on
Twitter. ;-)
Today, instead of asking him I thought, I could do the thing he
recommended a time ago: joining the users-list and here I am. Hi.

** my issue **

For scores with more than 3 or 4 instruments I would find it useful, if
I could put a short for the instrument-name in front of every line.
The first system has the instruments in front, but I do not find a way
to put an abbreviation of the names in front of every system across the
score.

Is there a helpful snippet anywhere in the documentation? Any Idea?


Thank you,
UCas
