Adding new field via the AET...

When I choose to create a new field via the AET I have to choose the object it applies to, like BUPA or CONTACT, for example. Having chosen BUPA I notice that it then displays the BUPA details and says that it's going to use the context node HEADER. If I wanted to use an alternative context node, like STANDARDADDRESS for example who would I go about doing that. Would I somehow have to create a BUPA2 object and somehow link this to the STANDARDADDRESS context node?.

Anyone.
