HELP_The simulation sequence of Kangaroo Physics

Dear all

I am trying to combine TWO points to ONE point when their distance is shorter than the distance I set, and once they combine together I'd like to drop down the new point. I have combine two points as first step. Could you tell me how to continue the next step after two points are combined together? Because the new point need several seconds to occur, if I set new Kangaroo Physics simulation, the TWO points will be selected again and drop down.

Sincerely

Apple :D
