Revising Flattened Routes?

Has anyone figured out how to update a manufacture flattened route after it has been generated?

It is pretty typical for us to change a connector or add a run to an existing harness.  I can manage to get the 3D version of the harness updated to look like I want, but have been forced to delete the flattened routes and re-do them.

Thanks in advance!
