Allow domain from block page permanently or temporarily

Please add buttons to allow a domain permanently or for 1, 12, or 24 hours temporarily to the block page that only appears for logged-in users with permissions to modify the domain list. This would help immensely with unblocking trackers for the purpose of unsubscribing from email newsletters. Currently, you must navigate to the control panel, add a domain, and, if temporary, remind yourself that you added it so that you can remove it later.
