Dear Server,

There is currently no easy way to do this, as the current key signature layout 
algorithms use glyphs as a fundamental unit.
That means that you either need to:

1) create your own glyph (moderately difficult)
2) rewrite the logic of the algorithm in Scheme, at which point you can make a 
composite stencil of a flat sign and the number two.

#2 is, in a crunch, likely your best bet.  I remember someone a while back 
wrote custom scheme code to layout key signatures but I forget who and when - 
searching online isn’t helping much, so perhaps the person who wrote the code 
is reading the thread and could respond?

Cheers,
