double notes in stemless notation?

[Ivo Bouwmans]

Hallo all,

I am writing four-part choral music in a stemless notation on two 
staves. Here's a brief example:

notesOne = {
\relative {
  \override Stem #'transparent = ##t
  gis'2 a4 b e,
}}
notesTwo = {
\relative {
  \override Stem #'transparent = ##t
  e2 e4 dis e
}}

When the voices have the same note - like the final e in the example 
above -, only one note head is shown (as expected). Is there a way to 
let LP still write two notes, close to each other (like in the case of 
two whole notes coinciding)?

Thanks for any suggestion!
