How to have one LC managed DNS for multiple LC clients?

I have two Liveconfig managed servers, A and B. Server A has LC managed DNS-, mail-, database- and webserver. Server B has LC managed database- and webserver. I created a reseller contract with the mail on server A, web and database on server B. I then log-in as the reseller and create an end user contract. I then add a domain for the end user. I only see external DNS as choice. While LC manages the DNS on server A it does not allow me to add domains there.

Is this a bug or missing feature?

Here I don't see such DNS template select field below "subdomains", nor any of the other services are editable in an existing subscription. In my case database and webserver are available on both servers but cannot be changed once the subscription is created.

I only see this choice in the "Add new subscription" dialogue box that appears when you click the "New subscription... " button of a client, but in that dialogue I don't see a choice for DNS template either:

Any news on this issue?

Must later now I gave it another try and yes it works now.
