Provide port_id instead of network_id during provision for network

I would like to be able to provide a preconfigured openstack port to the provision request insted of the network id for the network. I currently use this command to set the network

$evm.root[‘miq_provision’].set_network_adapter(0, {:network_id=>nic_0, :is_dvs => false})

but i would like to specify a specific port uid instead. Is that currently possible?
