string harmonics on sibelius

hi- does anyone know how to notate/indicate harmonics when writing for strings using sibelius?

As far as I know, there are two ways of notating harmonics:

1) Writing the note that should sound plus a little circle above. If you select the note, you can add the circle from the 4th layout of the keypad.

2) Writing the base note (if there is, for artificial harmonics) plus a "diamond" note where you put your finger to produce the harmonic. Just input both and then transform the one above changing the notehead type in the properties panel.
There's a plug-in for Sib to playback the correct pitch in this last case.

Ciao..
