How to find a used net stub which also has a nc attribute.

We add a small connection and the NC symbol to unused connector pins and then set the NC attribute to these connections.  All is well until one of my EEs deletes the NC symbol and ties the connection to ground without removing the NC attribute first.  Subsequent netlist generation flags this error, but unfortunately since ground is a global net, ALL the ground connections now carry the attribute and like a virus it is hard to remove.  I am investigating whether removing the attribute from the original connection segment will clean all the ground connections.  Any idea how to find it?
