Network Analyst Solve warnings

Hi,
when scripting a Network analyst route solver tool is there a way to get the warnings from Solve to show by using arcpy.AddMessage(?).
For instance when running solve from the network toolbar in desktop a warning can say:
No route for "A --> B" from location "A" to location "B".
No route for "C--> B" from location "C" to location "B".
No route for "D--> B" from location "D" to location "B".
