Configure connection init payload per socket subscription request.

I have a multi tenant app, and I need to pass through a token per subscription.
Currently I am using the ConfigureWebSocketConnectionInitPayload, that sends the appropriate token I require.
But this is variable is set per grapqhl connection, is there a way to sett this per CreateSubscriptionStream request?
or do I need to have some kind of singleton subscription factory.

```
GraphQLRequest graphQLRequest = ...
graphQlClient.Options.ConfigureWebSocketConnectionInitPayload = (GraphQLHttpClientOptions x) => { return new Dictionary() {
["token"] = "token value"
}; };
return graphQlClient.CreateSubscriptionStream(graphQLRequest);
```
