Turns in the middle between 2 notes

I would like to position ornaments (e.g. turns) in the middle between 2 notes, so that they stay in the middle even when the distance of the notes changes.

Now the position of the ornament changes when the distance of the notes changes because of the absolute distance of the ornament to one of the notes.

In many cases that doesn't look well, but sometimes even the musical sense will be modified (when the ornament arrives at another note.)

In the attached example the 2 turns show the exactly same positions in the inspector. But as I stretched respectively tightened the measures the second turn arrives below the next note.
