How to manage certificate entries

Hello,
I recently started using RDM also to save and manage our certificates.
I saw that when entries expire, they turn orange. I usually then make a second entry, I append 02 at the name, then I have them sorted and visible.
However, I can't get it quite as I would like it:
I know I can hide the entry. But...

Let's assume a certificate is going to expire at 01.05. I should get some kind of notification 30 days before according to the setting under notifications, but I never saw any notification.
So if I let entries to hide, then I won't notice the certificate expire, as it will turn orange WHEN it expires... and at that point, it will be automatically hidden.

I would like to do following if possible:
Get an email notification of the expired certificate if possible, or at least a popup window when logging in, or some kind of very visible message. Good idea would be maybe to receive a notification once a week for a month about the entry, or at least configurable.
The certificate should remain orange from the notification delay (default 30 days) until the date it expires, at which point it should get hidden.

Essentially I would want to get a decent notification(s) about expiring certificates.

I hope that makes sense.
