PowerShell Set-AuthenticodeSignature Support?

[JustinGrote]

Would it be possible to adapt this to replace how Set-AuthenticodeSignature work in PowerShell? I'd like to sign PowerShell scripts but not have my private key leave the Azure Key Vault. Based on previous discussion, it seems I can get the same digest and get it in a format that I could base64 attach to the bottom of a script.

The signing process puts the signature as a comment block at the end of the script.
