Please add option to disable the blocking timeout for a single IP address only. This would allow the block to be temporarily lifted for a specific IP address.
The logic behind blocking requests and allowing them, happens at DNS level, which is a “resolver” (FTLDNS) on port 53 (industry standard).
While it sees who inside the network requested the specific address, the disabling of blocking is a “global” thing. It’s on or off and it applies to all the devices running queries through that DNS server.
You could leverage a combination of client+group to use specific ad lists per IPs, that way the specific client has less or more filtering.
Not quite technically what you need, i know but single client disable/enable is not something that can be done (without involving serious local firewall rules and timers and elevated privileges - all out of scope for this project).
