Auto Renew OpenVPN Server Certificates

[Wastapi]

Recently my Open VPN Stopped working. My VPN Client did not explain why... just timing out. I searched all over the place. Only to discover that the OpenVPN Server Certificate was expired. :/

So I clicked the Renew button in System > Certificate Manager
All worked fine again.

QUESTION: Is there a way to AUTOMATE this so the cert gets auto updated a couple of days before expiration?
