Azure VM: Adding a Reserved IP address to an existing VM

Question

What I have read so far on the web is that there is no way to add a reserved IP to an existing VM (unless I recreate the VM which I am trying to avoid). However, I have noticed

Answer 1

New-AzureReservedIP -ReservedIPName "nameIP" -Location "East US" -ServiceName "azureA2vm"

Get this:

New-AzureReservedIP : A parameter cannot be found that matches parameter name 'ServiceName'.

+                                                                      ~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [New-AzureReservedIP], ParameterBindingException
