Linetypes in Revit Architecture

Question
Can Revit create linetypes with text along the line or symbols to represent stormwater or various other services?

Answer
The short answer is no. You can create a line based detail component, but the text symbols would need to be a nested symbol family. I've created one which enables me to set the value for the text to anything I want as a Type parameter. You can't currently do this for a curved line though...
