Corridor Clipping in PowerCivil ss3

Is it possible to get corridors containing closed components (Tunnel Sections) to cut against each others smoothly? I have tried to use "Add Clipping Reference" under Corridor Meny, but the result is a 2D, from above,  projected cut. The cut is vertically made, but I want the cut to be performed so that the rounded shapes of the tunnels meet in 3D.
