displaying value of tied note at the end of line

[zbigniew]

Hey, 

Im using "Completion_heads_engraver" to break long notes at the end of line
 in some long cadenzas and sometimes it comes up with a complex result 
(multiple ties, dots) which is hard to read,
 
is there a way to display the value (as number or note) of the note which is 
being broken e.g. just above it at the end of the line? 

thanks in advance for any ideas
