Turning off the auto join in free hand tool ??

Is there a way to turn off the auto join with the free hand tool/ I am trying to sketch and need to do lots of small free hand dots and marks for depth and it is driving me crazy trying to just do a small dot with my Bamboo pen. It keeps joining and making lines- Argghh- I've gone into options and played around with the freehand tool settings but can't find anywhere to just turn it of completely,

Would appreciate any help
