This design review is based off of the issue created in the Powershell Design request: https://github.com/Azure/azure-powershell-cmdlet-review-pr/issues/1250. There, I have listed a more extensive list of use cases and requirements for being able to set the property. Since the property itself is a struct with 2 fields, it may be best to flatten that struct. I have also listed this on the Powershell design request linked above.

Additionally, please note that the Swagger changes and SDK changes have not been merge to their respective feature branches, and the PowerShell features also have not been implemented by the PS team.
