Custom IaaS WF extensibility

Hi

I have extended a custom blueprint which provisions VMs to call a custom vCO WF. Since we are on vCAC 5.5 , I have used the vCAC plugin WF "Assign a WF to blueprint and it' virtual machine" to call the custom vCO WF from the blueprint at the VM provisioning state.

The custom vCO WF takes the VM name as the input . How to pass the VM name of the VM that has been provisioned by the blue print and pass it on to the vCO WF ?
