Hi,

is it possible to add custom fields to certificates during the creation using elasticsearch certutil [https://www.elastic.co/guide/en/elasticsearch/reference/7.8/certutil.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.8/certutil.html)?

My Use case: I want to create new client certificates for filebeat and I would like to add custom attributes to the certificate created.

Thanks
