This might be broadening the scope of the original concern, but as food for 
thought:  

One would want to control the timing of the HH closing for *artistic* 
purposes... the HH closing can make for rhythmic expression (and often does, in 
live performance)....

That said, however, the automation of the above (in lilypond) may be outside 
the scope of what the app is intended for (primarily score engraving).  Correct 
me if i'm wrong.
