cadenza question

[Jule Slootbeek]

Hi
I have a Solo + SATB + Piano piece, (in 4/4) and in the last measure the soloist has a cadenza of 6 beats while the chorus sustains the word "home".
Here's the solo notes:

\cadenzaOn bes8 ( des4 ces8 \cadenzaOff [bes8 f8 as8 ges8] [as,8 ) f'8] [es8 () des8] 

for the chorus i had to use 
| e1 ~ e2 | to complete the 6 beats, can i make that one note? 
\cadenzaOn e1 \cadenzaOff doesn't work
does anybody know if it's at all possible? 
thanks,

Jule
