You could use more or less the same solution as is indicated in 
http://mail.gnu.org/pipermail/lilypond-user/2002-May/001350.html
but inserting \slurUp and \slurDown commands instead of 
tempo indications. Note that the property settings and the
music have to be in the same Voice context to give the desired
result.
