A couple of questions about lines and trills
In the Lines palette (see attachment), I don't see the one thing I'm looking for: a line (either solid, dotted, or dashed) that starts open-ended on the left side and ends with a small downward 90-degree turn. It would be used for indicating the end point for particular events. Is there such a line somewhere else beside the Line palette?
Also in the Lines palette is the trill with attached wavy line. Is there any way to stick an accidental between the "tr" and the wavy line (in order to define the interval between the trilled notes)? I realize the alternative is to use the Ornaments palette where the "tr" and the wavy line are separate elements.
