Text spanner padding

[Andrew Bernard]

I am attempting to use a text spanner as an indicator for a repeated section. I need it to stop at the barline, and not on the next note. Shortening it by using padding on the right affects the first line as well, which is not wanted. How does one do this properly?

And my usual question, is there a proper way to do this rather than trying to bend a text spanner into it?

Sometimes I may want 17x or 5x, etc, not just twice, or 3x. And I want the dashed line effect.
