divide trail / trajectory

Hi everybody!

I'm doing some experiments with Locust and recording the trail with the Kangaroo component (Trail) and I would like to divide the tractory made by the points. It is like if was "branching" this lines by dividing these points randomly.

Does anybody know how can I make this branching?

My definition is attached to this file, you have to push the button to have the trail to be tracked.
