With the Professional and
Beginner versions, you can use the lyrics fast encoding window to
copy identical lyrics lines. First, encode the first line. Then
select the whole text ("*" symbols stands for notes
without lyrics) and copy it. After you click "Apply",
go for example on line 2 (menu in the upper part of the window)
and paste the lyrics in the text area. The same copy/paste can be
made from your text editor, if you already have the lyrics in
text format. You will just have to separate the syllables with
"-" and everything will be all right.
