octave transpositions ("8va")

Ijust posted the following message to the Wish List:

{It would be nice to have the ability to create 8va markings in the traditional style ("8va-|" followed by a dashed line above the notes). Best implementation would be to select the notes you want to raise (or lower) an octave, and then click a button.}

Has anyone found an easy way to kludge this? Performers don't generally care for the simple clef with an 8 superscript that NWC currently uses, as it doesn't continue to remind one to transpose. Boxmarks has an 8va figure, but it doesn't extend very far and doesn't mesh well, in my experience, with text dashes as extensions.

G'day William,
while its not perfect, I usually use 4 text entries:

1. The first is a centre justified 8va placed left of the first note in the section.
   
2. The next is a left justified row of ---- that is shorter than I need and placed immediately after the first note of the section.
   
3. The third is the Boxmark symbol to finish the 8va section, this is centre justified at next note/bar and placed just prior to the last note of the section.
   
4. The last is another row of ---- but which is right justified to just between the symbol from point 3 and the last note and long enough to overlap the row in point 2.
   

All vertical positioning is set for correct alignment.

Sometimes I can dispense with point 4 but this takes some judicious use of print preview.

I fully agree that a formal 8va, 8va bassa and 15ma function would be preferable.
