Azure Durable Functions - Unable to change Task Hub Name to support Side-by-Side versioning

I'm looking into implementing the Side-By-Side Azure Durable Functions versioning pattern described here: https://docs.microsoft.com/en-us/azure/azure-functions/durable-functions-versioning

I have a FunctionApp deployed that currently uses the default HubName DurableFunctionsHub. I've read through the documentation above and it seems that all I am required to do is provided the following json in the host.json file:

{ 
   "version":"2.0",
   "durableTask": {
         "HubName": "TaskHubV1"
   }
}

When I deploy the new host.json file I can see in the portal that the host.json file has the changes above, but the storage container does not contain new Blobs, Queues or Tables prefixed with the HubName TaskHubV1. The Screenshot shows the storage container contents:

Durable Function Storage Screenshot I was expecting additional Blobs, Queues and Tables to have been created using the HubName above as a prefix e.g. Table Storage: TaskHubV1History TaskHubV1Instance

Could it be that HubName changes are not currently supported by V2 Functions?

The formatting for V2 has the "durableTask" property under "extensions". Could you try,

{
  "version": "2.0",
  "extensions": {
    "durableTask": {
      "HubName": "TaskHubV1"
    }
  }
}
