Overriding existing message route

[mvoronin-eastwind]

While moving from NSB 5 to NSB 7 we faced to issue with overriding existing message routes. In NSB 5 we were using configuration-based rouing and were able to route all messages from assembly to one endpoint and single message from assembly to another endpoint e.g.:

<UnicastBusConfig>
  <MessageEndpointMappings>      
    <add Messages="MessagesAssembly" Endpoint="endpoint" />
    <add Messages="MessagesAssembly.SpecificMessage, MessagesAssembly" Endpoint="another-endpoint" />
  </MessageEndpointMappings>
</UnicastBusConfig>

Now in NSB 7 we are trying to do the same with file-based routing:

<endpoints>
  <endpoint name="endpoint">
    <handles>
      <commands assembly="MessagesAssembly" />
    </handles>
  </endpoint>
  <endpoint name="another-endpoint">
    <handles>
      <command type="MessagesAssembly.SpecificMessage, MessagesAssembly" />
    </handles>
  </endpoint>
</endpoints> 

but it throws an Exception:

Route for type MessagesAssembly.SpecificMessage already exists.

Before PR 4041 there was argument bool overrideExistingRoute in method RouteTo of class UnicastRoutingTable:

public void RouteTo(Type messageType, IUnicastRoute route, bool overrideExistingRoute)

but now it's just

public void AddOrReplaceRoutes(string sourceKey, IList<RouteTableEntry> entries)

Is there any alternative to bool overrideExistingRoute in current NSB version to override routes for specific messages? Thanks.

@mvoronin-eastwind: @timbussmann has taken over the File Based Routing as a community project. If you would like you can raise an issue about enabling file-based routing to provide the type of override you are seeking here: https://github.com/timbussmann/NServiceBus.FileBasedRouting

Otherwise, I would encourage you to switch to using our routing API which allows you to override routes: https://docs.particular.net/nservicebus/messaging/routing#command-routing.
