Ownership manager in 10.1 not allowing to add at node level

Hi experts,

     I am facing an issue with BPC 10.1 ownership manager , I am not able to add a node in the ownership hierarchy. The option I am given is to add sibling or children but not to add at the node so that the hierarchy rollup which was available in 10.0. When I tried add the sibling and then tried to delete I was still not able to get my result. Is this a normal behavior, can somebody please tell me how to add a holding company. I have to add B and C under it.
