When reservations are auto-renewed, the new reservation sets the auto-renew to false. That seems like a less than optimal experience for those who want to do ongoing 1-year reservations.

As of this idea submission neither Azure CLI or Azure PowerShell appear to support modifying the renew attribute by script for an existing reservation.

We manually set the renewal setting for hundreds of reservations figuring it was a 1-time activity. I suppose that turns us now to the REST API. We prefer interacting with the scripting options and would love to see Azure PowerShell support modifications of reservation auto-renew attribute.
