Un-Grouping a routing using CA02

I have many parts that have goruped routings. I need to begin removing some part numbers from the group and give them a stand alone routing. Is there a way to simply ungroup individual routings?

I have been told that I would have to delete the individual routing from the group and then recreate it as its own routing again, If this method must be used is there a way to copy the original routing before deleteing it from the group?
