ORD SUDA Nodes and Conduits

I have clients that use different mannings numbers for Reinforced concrete pipes.  Is there a way to create custom prototypes so that these differences can be accounted for?

Also, I am trying to bring all of my InRoads SS4 drainage nodes forward into ORD.  When I open my 3D cell library, I receive a warning that my file is read only because of SS4 data. I didn't realize SS4 info was stored in this cell library.  Do I need to redraw all of my node cells for ORD?  I cannot find any training info for ORD on building SUDA standards.  If there is a training somewhere on ORD SUDA standards, I would be grateful if someone would point it out to me.

Thanks,

Jason
