Data request question in the sample "chassisRackVSphere-service" of SDK 5.5

Hi,

In the sample "chassisRackVSphere-service", in java code "ChassisRackVSphereDataAdapter" use the

initializeHostRelations();

to fake relationship with hosts and chassis.In this function,it makes every data ready to make it easier to setup.

But,in real development,this process to make every data ready may take a long long time(in my case,it actully takes 3 minutes to make every data ready).

So,is there any way to request data what I need?but not to request every data of all hosts and chasis relationship.

For example, in the pic below, I select the  "Chassis 1", then start to request data only under "Chassis 1",then I select "Chassis 8", it start to request relative data.
