How do I use street elbows and regular elbows in the same assembly?

I have an assembly with multiple routing subassemblies in it.  It would seem that you can only have one type of fabricated pipe and one type of tubing in an assembly containing routing subassembiles.  It would also seem that you can only have one type of 90 degree elbow in an assembly containing routing subassemblies.  I need to do both.  Does anyone know of a work around?SolidworksRouting
