arrow director texts, labels, annotations

[piotta]

I noticed from the ver. 2014 (the 2013 I skipped it) that you can insert and customize the ends of guidelines added to the text notes by offering the possibilities to vary it as an arrow at 30° or full etc...
I wonder if it is possible to customize the graphicism of the arrow by changing its end and by putting a ball or a hyphen a little often? I can't locate in the project browser the following families and then edit them?? ! ! . ..mad:
