Transportation - shipment mass re-routing

Dear Community,

question / challenge on the topic of shipment routing and re-routing:

A new Route was recently entered in our system with incorrect transit data (ex: 1 day for transit instead of 3)

Since we are using auto routing, as a direct consequence hundreds of shipments lines were routed to this route.

question:

- if I deactivate this new route, will all shipments be re-routed automatically to another route ? if not, is there a way to tell the system to mass re-route via an UBE for instance?

- if I change the transit days on the route, will the (already routed) shipments be updated with the new transit time?
