Single note slurred to chord tone

[Doug Asherman]

I'm seeing something that I'd like to be able to fix, but I don't know 
if it's possible.

I've got a case where I want to slur from a single-note g to an a that's 
part of a chord. But the slur goes from the a to the lowest note of the 
chord. I can fix this by setting \slurUp, but because this is one of two 
voices on the staff, that's not workable.

I've appended some lilypond source at the end of this letter that 
demonstrates the problem I'm having.

Any help would be appreciated.

Thanks,

Doug
