Can't connect several LineToBeam to Assemble Model

Capture

Hi, I am using Karamba for the first time. I want to connect several LineToBeam to Assemble Model at the same time, as shown in the picture. However, the software only allows me to connect one LineToBeam to Assemble Model each time. Is it because I am using the trial version of Karamba? Any help would be appreciated.

LMB+Shift+Drag = Create a new wire without erasing old wires

It solves my problem. Thank you!
