Missing piping elements plus 14inch in the library on solidworks in module routing

Hello

I'm making a 3D model with the Solidworks Routing module

and I'm in the process of piping the model and I need 18 inch and 16 inch pipes with of course Tees, elbows, Reducers, flanges and valves with these inches, but in the library we are restricted to 14 inches max.

if possible to know how to increase diameters in the library.

Kind regards

 

I believe that just like welded construction profiles, you can create/decline/modify the parts you need. In this area, a family table is interesting, knowing that the essential for routing, it seems to me, lies in the connection points.
