Right I just upgraded my NPM to 12.1 and saw that they came with the NEW Perfstack where you can get a lot of great info in a new fast view. 
So my thought was first ... YES now I can make a new view there will show all my MPLS line in one view.
But I might be disappointed because I cannot see this option in the Perfstack so far....
So can this be done or I am wrong here?: )
Hope some one can share some light on this matter and help me
