Whitelisting blocked domain for a specific duration

I feel like it would make sense to whitelist a domain for only a specific duration. Consider the following use case:

I received an e-mail containing an unsubscribe link that lead to a domain blocked by pihole. Now, I of course want that request to go through, so I can successfully unsubscribe, however, all subsequent requests should be blocked (as i’m assuming there are other illicit requests being sent to that domain, so I don’t want to whitelist completely).

I was thinking of having the option to whitelist for (1 hour / 24 hours / 7 days / 30 days / 365 days / indefinitely)

Thanks!

Just to clarify, would this feature be different from the Disable Blocking feature through the Pi-hole Dashboard that lets you disable blocking for custom amounts of time? That would make sense to have the distinction to either temporarily whitelist all blocked domains or whitelist a specific one like you described.

Cheers
