Hello! Thank you for submitting this issue. Trying to understand the need better; do you have any ideas as to how custom fields such as ResponsibleTeam would be populated by the signer? I have the following idea, and I'd like your feedback:

Add custom logic to commandSigner.Sign() to listen for custom K8s annotations (that aren't already used for overriding defaults) on Certificate.cert-manager.io/v1 objects that map to Command Metadata Name fields.

For example:

apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  annotations:
    command-issuer.keyfactor.com/ResponsibleTeam: "theResponsibleTeam@example.com"

If you have another idea, please feel free to let me know!

I'm a kubernetes operator, use annotations to pass datafield to keyfactor sounds logical to me, but I have no idea how custom fields in keyfactor works.
