Feature Requests SSL expiration-only checks

I have quite a few domains which I only have monitored to check if the SSL certificate is about to expire, I have these set to the maximum of 1 hour interval so that they don't use up checks too frequently. From another SSL related post here I think the SSL cert check is only done very 10 regular checks, so in theory this means that every 10 hours these domains' SSL certs are being checked.

I don't really need these being checked as frequently as every 10 hours, once every 24 would be frequent enough. So having it do a regular check every 1 hour for these domains is also unnecessary and uses up credits.

I wondered if an option to add a check type which is only for monitoring SSL certificate expiration would be viable? This would be set to be checked on a longer timescale of at least a few hours, likely more like once every 24 hours. If adding a specific check type isn't viable then could the available intervals for checks be increased to include options above 1 hour? With the SSL expiration check occurring every 10 regular checks then an interval of 2 or 3 hours would mean an SSL check would occur every day or so.

As a clarification of why I have added these SSL expiration checks to Updown.io it is because LetsEncrypt are planning to discontinue expiration notification emails: https://letsencrypt.org/2025/01/22/ending-expiration-emails/ They are recommending people use services like RedSift or similar for monitoring expirations but I would prefer to do this via Updown.io instead, perhaps there is a good opportunity for Updown.io to gain customers (See LetsEncrypts current list of services they're recommending: https://letsencrypt.org/docs/monitoring-options/)

Thanks!
