While I can create a new Inbox Rule, it's not possible to run this rule against all messages in my Inbox already that match the criteria of the rule.
Is it possible to update this to be more akin to the Outlook / Exchange inbox rule engine?

This feature is sorely missing - when a rule is created, we should at the very least have the ability to run it right away on our existing mailbox.
Having the ability to run any of our rules manually would be a huge time saver. For now, I have to manually do what I want a rule to do for anything that's currently in my inbox, which is a really big hassle that shouldn't exist.
