Hi Silvano, HyperLynx 6.1 has this new feature. After selecting a net on BoardSim, if you click on File menu, one of the options is to export the selected net to LineSim. The net will be exported as a LineSim file with all stack, net, and driver/receiver parameters. Vias are exported as capacitors. In the LineSim file, you can try various what/if scenarios. I have found this features very useful.

This will gratify some people and astonish the rest. ....
