Formatting of lyric syllables

[Till Rettig]

Hi all,

is there a way to change only part of a lyric syllable?

The issue is, that when having 4 repeats with 2 voltas, the fourth 
stanza (in the second volta) is on the same level as the third in the 
first volta. I would like to indicate that the text belongs to the 
fourth stanza, though.
Ideally I could shift the level of the text down, so it would appear as 
the fourth stanza, but so far I just added: "(4.) syllable", the first 
part indicates the stanza. Now I would like the number to appear bold. 
Is there any chance? markup commands won't work inside of quoted text...

Greetings
Till
