Support specifying a cert thumbprint on Windows

Hello,
I wanted to switch from the Azure PowerShell to Az cli, because packer supports use_azure_cli_auth.
Tested locally - things look great. I started to updated a release pipeline and ran into an issue:

**az login --service-principal** requires a pem file on Windows. My expectation was that I will be able able to pass certificate thumbprint on Windows, similar to https://learn.microsoft.com/en-us/powershell/module/az.accounts/connect-azaccount?view=azps-12.0.0#example-7-connect-using-certificates

Unfortunatelly, the following example is not very useful:
https://learn.microsoft.com/en-us/cli/azure/azure-cli-sp-tutorial-3#convert-an-existing-pkcs12-file

Are there plans to support specifying a cert thumbprint on Windows?
Thanks,
