VGPU support with multiple physical GPU on same board

Update:
If I specify SHORT_ADDRESS directly in the template, it is possible to create a VM using another BUS, however, as the FUNCTION is explicit, I can only create a single VM with the same template

onetemplate show 3 -x

  <PCI>
      <BUS><![CDATA[45]]></BUS>
      <DOMAIN><![CDATA[0000]]></DOMAIN>
      <PROFILE><![CDATA[nvidia-720]]></PROFILE>
      <SHORT_ADDRESS><![CDATA[45:00.4]]></SHORT_ADDRESS>
    </PCI>

onevm show 30 -j
