Deal with email messages that aren't quite spam

The spam button is good for marking spam messages and banishing them to the spam folder. I'm looking for a quick way to deal with messages that in my opinion are not quite spam. Mostly advertising emails from companies that I've dealt with in the past. I don't want them banished to the spam folder, but I don't want them cluttering my inbox. I can: - Select a message. - Select Mail:Settings:Rules - Add rule. (Conveniently the message's from address is already entered.) - Select the mailbox I want to move the message to. - Select OK. But that's more time than I want to take. I'd like a quick button or pull-down to add this kind of rule quickly and be done. Does anyone know of an extension, shortcut, automator, or script that does this? Hopefully, some script that adds or edits rules? I've seen several scripts working with sending messages or moving messages, but haven't found any that work with Mail's Rules. Aren't there any script handles for the rules?
