Did you take a good look at the SRM Plugin for vRO then?
(8.3 plugin does not mean that it is only for vRO 8.3)
Why any other possibility?
You have SRM, you have vRO, there is a free plugin from VMware to link those together and solve your question.
I cannot image why you would prefer a different solution.
But, if you like, you can take a look at how the plugin works and then discard that and do it yourself. 😉
