Feature Request: Better multiple account unlock

Hi All,

So right now, in order to have both a personal and work account unlock simultaneously, you have to set the master password to the same for both. This creates issues if your personal account master password isn't strong enough, and also just feels... icky. reusing the password. 

Would be nice to see the ability to save work account password in personal account, then tell 1password to automatically unlock the work vault with those credentials.
