@Wayne-Workman unfortunately we will not add this. The ssl directory where your private keys are stored, and should never be accessible via the web GUI. That presents a massive security risk as a single bug in the web GUI could provide anyone with access to your private certs; arguably the most sensitive data on the server.
As the saying goes, security and convience are usually at opposite ends of the spectrum; and this is one thing we will not compromise on.
Exporting your keys as root using ssh is the preferred, and only way, we will support.
