Write lyrics aligned to one voice, but display elsewhere

[Nils]

Hello list,

When writing 4-voice chorals (2 voices each in 2 staffs) and hymns it is good 
style to display the lyrics under the complete system, under the second staff, 
but align them to the melody which is normaly the highest voice.
How can I do this? I want to write my lyrics for the melody, with automatic 
syllabe positioning (not including durations in the lyric line) but shift the 
whole lyric line down, under the lowest bass notes.

Greetings,

Nils
