install LDOM by importing list-constraints .xml file

But I'd like to assign the MAC address of vnets assigned to the LDOM. By default ldm list-constraints doesn't grab the MAC address of a previously built VNET.

example:

<Section xsi:type="ovf:VirtualHardwareSection_Type">

          <Item>

            <rasd:OtherResourceType>network</rasd:OtherResourceType>

            <rasd:Address>00:14:00:00:00:00</rasd:Address>

            <gprop:GenericProperty key="vnet_name">vnet_name</gprop:GenericProperty>

            <gprop:GenericProperty key="service_name">vsw0</gprop:GenericProperty>

            <gprop:GenericProperty key="pvid">222</gprop:GenericProperty>

            <gprop:GenericProperty key="vid">12,2,102,103</gprop:GenericProperty>

            <gprop:GenericProperty key="device">network@0</gprop:GenericProperty>

            <gprop:GenericProperty key="id">0</gprop:GenericProperty>

          </Item>

        </Section>

since these are "gprop:Generic Property" would it be possible to add another gprop field thusly:
