How to create a raised table?

Hi all,

I am coming to OpenRoads Designer from a Civils 3D background and have what could be a somewhat British problem.  I'd like to know how I would create raised tables as in the screenshot below (modelled in C3D).  In C3D I would use varying height kerb assemblies to go up from 100mm upstand to 6mm and down again with the vertical profile to create my ramps and table, is there a way I can use parametric constraints on my templates to do this in ORD?
