Reconfigure VM to modify SDRS

Is there not a way to set the SDRS rules for a VM using a ReconfigVM_Task?  I see some examples using ReconfigureComputeResource but I need to use the _Task version and don't know what cluster resource to use (the cluter that VM is in???).

When I use the vSphere client and make this change manually, I see a "Reconfigure virtual machine" task in the log so the UI must be doing something similar.

I need to do this using the Java.

Thanks
