arbitrary SpanBar control

[Kieren MacMillan]

Hello all,

I would like to be able to control “at runtime” the SpanBar immediately below a 
given Staff, regardless of whether it is inside a StaffGroup [with its own 
SpanBar settings], etc. All of the solutions I’ve found for controlling 
SpanBars are more global (e.g., 
http://lists.gnu.org/archive/html/lilypond-user/2015-12/msg00784.html), and I 
have yet to find a magic incantation on a more local level.

Can someone point me to an example or documentation with a solution, or an 
explanation of why what I want is currently not possible in Lilypond?

Thanks,
Kieren.
