It's very simple - create a delta terrain at the depth of your topsoil and then set that terrain as the active terrain and re-cut your cross sections. The earthworks slopes will then target the lowered terrain. So if you have 300mm of topsoil create a delta terrain at 0.3m depth and set that terrain as the active terrain.
