Feature request: treat intranet sites as being on my whitelist

I'd like to request a new feature on the RescueTime logger: the option to treat all intranet sites as being on my whitelist by default.

This would save me having to add each new intranet site to the whitelist as I realize that I'm using it.

(It might also boost corporate adoption, since it lets users be much more certain that they're not "leaking" sensitive URLs from within their corporate network to RescueTime)
