Expiration reminder emails on entries

Hello,
It would be extremely handy to have the system send email reminders about upcoming expiration dates on entries. We currently track expiration on domain names, SSL certs, service accounts, software renewals, etc.

Could the system be enabled to send email on an interval similar to the following:
- 30 days before expiration an email is sent
- 7 days before expiration an email is sent
- 1 day before expiration an email is sent

Thanks,
-Steve
