white listing by secondary domain name?

Edit Subject

I'd like the option to apply settings to groups of domain names; currently, for example, I must whitelist each deviantart member (Such as ryugaxryoga.deviantart.com) separately, even though I've already whitelisted www.deviantart.com. While I can understand not automatically unlocking related sites- many places host a combination of safe and dangerous sites- it would be useful if users could do this manually; even better would be the option to go through a list of related sites and check/uncheck certain entries (IE clearing the checkbox for fuzzybunnies.example.com to whitelist it while leaving pornginas.example.com on the blacklist).
