Is it possible to track who opened a private prezi?

Ok. So on a Private Prezi you can add people to view the presentation. My question is, does Prezi have the functionality to track the view count of each individual person that has been added by the creator? This allows me to see if the # of people I add are actually using the presentation

So for example: I create a neatly layed out Prezi featuring a specific topic that NEEDS to be read by each person I add. Part of this is Health and Safety but it is also on the Legal side.

I add 20 people to this Prezi. I can now see it being used, but I have no idea if the # of views are from 5 of the added or from everyone I specifically added.

Is this a possible feature or is this something Prezi is yet to implement?
