Muse sounds Snap Pizz. working?

Hi,
I am trying the muse sounds on MS4, the sounds are really great, and the sul pont./tasto on the strings are wonderful. It says in the description that it supports Snap (pizz. Bartok) as well as col legno, but it doesn't seem to play it (snap with sign, legno with text). I couldn't find any documentation on the trigger text...

Has anyone managed to make it play snaps?
Also, I see that it supports portamento as glissando between two notes, but often a portamento is written just to approach a note, and I see that muse sounds doesn't play it... it would be great to have it in future versions since it is pretty standrad notation.
