Custom Rigging in MotionBuilder

LmxL

Hi,

Since this week I have to use Motionbuilder  and I have an issue with the characterise / rigging tool. 

I can add the control rigg on all the basics bones of my character but I dont find a way to add control for all the extra bones , like the bones of the dress, the hairs, jewel ....

Anyone have a solution ??

Thank you
