The 16.5 Allegro Global Route Environment (GRE) has been enhanced by what we call a 2 Point Flow. These flows provide the benefit of both a guided flow and the simplicity of a default flow.
The 2 Point Flow:
For example, if you wish to provide 'no' guidance to some bundles, let the router pick the best path for all the members. So, you route the bundle spatially. Suppose you don't like the way the route exited the component. You wanted it to exit north instead of west as it chose to. Change the bundle's properties to be 'Guided', and place the gather points at the appropriate exit locations. Run the router again and you should see the routes exit the component in the desired direction, yet still be able to route on their own in between the gather points.

In GRE, click the RMB on the bundle and select Bundle Properties > General:
