Use vCO to change Virtual Machine Owner

Hello,

Has anyone discovered a way to change the owner of a VM thru vCO?

I can update the IaaS record with the new owner:

//Find the vCAC Owner Object
var modelName = 'ManagementModelEntities.svc';
var entitySetName = 'Users';
var filter = "indexof(UserName,'" + Owner + "') gt -1";
var orderBy = '';
var top = 1;
var skip = 0;
var headers = null;
var select = null;
var entity = vCACEntityManager.readModelEntitiesBySystemQuery(vCACHost.id, modelName, entitySetName, filter, orderBy, select, top, skip, headers);
System.log("User Name - " + entity[0].properties.get("UserName"));
//Setup new links
var links = {  Owner: entity[0]
}
//Update VM with new Owner Link
var updateProperties = new Properties();
System.getModule("com
ibrary.vcac").updateVCACEntity(vCACHost.id, modelName, "VirtualMachines", vCACEntity.keyString, updateProperties, links, null);

Is there anyway to update this information in the CAFE database as well? The owner field on the custom resource object is read-only, and there is no method for setting the owner.

Thanks,

James
