kadego,
azreal is right on the money for adding (or removing) leaders from exsiting notes as I'm sure you've already tried.
Based on what I've seen from our new nx2 drivers (currently moving from v18 to nx2)too many of them haven't figured out how to create text with multi leaders. I'd hope that isn't the case here but if so, multi leader can be created by the same click-drag method as text with a single leader.
Probably information overload, if so please forgive.
