Karamba BeamID

I am following a tutorial on creating and analysing a truss. In the tutorial the Beam to Line elements have a BeamID. This beamID is important because later for the materials block the beamID is used to assign an element to that line.
I guess in 2019, there is a change to the way this is done. Any ideas how to add beamID, that later I can use as the Element Identifier for the cross section component?

This is a link to the video I am following: https://www.youtube.com/watch?list=PLuMiJ9JUcOVl6pVW34bRT8yCzXW567vLF&time_continue=157&v=I_faYYbn4Rk

Hi @t.donov94 the tutorials are quite old and we are working on updating them at the moment. The element id input works the same as the beam id.
