use wilcard in PasswordManagerExceptions policy

[CedricLevasseur]

I'd like to use wilcard in PasswordManagerExceptions in policies.json.

My company is discouraging Firefox and blocking the PasswordManager with a Policies. We are encouraged to use the corporate passwords manager for all the compagny websites, but my personal passwords already stored are now jailed. 
It would be great if policies.json could use wilcard, so that my company would prevent the use of the Firefox password manager for its dedicated websites only.

{
  "policies": {
    "PasswordManagerExceptions": ["https://*.mycompany.com",
                                  "https://*.mycompany.io"]
  }
}
