lyric extension line and tie after repeat ending

Dear users and developers,

What is currently the best way to draw a lyric extension line?

The original piece is Donau of Strauss:

I have drawn

  • the ties by using “laissez viber tie” with changing “Start offset” and “End offset” and
  • the lyric extension line by typing “_” into lyric popover.

Have I done correctly?

Thanks in advance!

Yes, that’s really the best way at present.
