Add Custom CSS name in Pointer Box Info

Awesome plugin. Would it be possible to add a custom css box to the better admin pointer box info meta items. whatever the user inputs for this field, would be used as a class for the pointer container to uniquely identify this specific pointer so it can be target via css. Now every pointer can have a different style if needed instead of 1 size fits all.

I guess, maybe you could just put the pointer ID as a class of the pointer container, and no extra input by the admin would be needed.
