Melody transfer / connecting notes with lines

Is it possible to draw lines on a score that do not correspond to playing techniques such as glissandi? And, in particular, dashed lines?

Context: I want a dashed line to indicate transfer of melody from one vocal part to another, as in the attached image:

No, you can’t yet draw arbitrary dashed lines between notes. You can draw a straight glissando line and hide its text (via the Properties panel), but obviously that’s a workaround and it’s not dashed in any case.
