Q1 - What is the exact nature of the problem trying to be solved with this request?

A1 - We want consistent disk names presented to the VMs so we can change our build process to not rely on sd names that can change across reboots.

Q2 - List the business requirements.

A2 - I'm not sure how to answer this.

Q3 - Do you have specific timeline dependencies?

A3 - Not really, we can manually set this parameter or possibly use powercli, but ideally we could just have this set during build.

Q4 - Can you please explain us the what are the functional requirements? If test cases can be provided this would be even more ideal.

A4 - Pretty basic, just want to be able to build a new VM and have the advanced parameter set.

Q5 - Would you be able to assist in testing this functionality if implemented?

A5 - Maybe...I'd have to figure out how to get a test environment setup.

A feature request already exists to get this added, but its had zero traction -
