Yes, I would be interested in that feature as well.  I would like to say I
could help, but I am really out of time.  I could possibly review any
changes if you are able to make a first attempt at modifying the code in
quiver3.m.  Could you prepare a patch and submit it to the patch tracker? 
The patch tracker is at https://savannah.gnu.org/patch/?group=octave.
