Lyrics linked to Performance

[Jakov]

Hi, PA3X owners!
I have a question: what should I do to connect Performance with lyrics?
When I'm in live playing, I use Songbook or Perfomance list. I know how to link lyrics with song from Songbook. There is a problem with linking lyrics with song from Performance, because I don't know how to save Performance and linked lyrics. After usual saving (Shift+Perormance), everytime I choose different song from Performance, linked lyrics are gone.
So, what to do to save some lyrics with a specific Performance and to stay thatway?
P.S. Manual says nothing about it...
