Kangaroo2 simulate two objects' physical action

Hellow all<

Recnetly i got a problem that i cant simulate two tensegrity objects together, but one unit is fine , im wondering that if there is any kangaroo tools which can fix the point on the other one and works functionally , my situation now is kangaroo will calculate those objects seperately.
thanks all
