Unlock feature for non-admin users

First of all, I’d like to thank you for making this awesome plugin!

I’ve installed the WP Security plugin on a website of one of my clients and it is working perfectly. This website has almost a hundred registrered members, of which a select few have the capability to manage users.
Once in a while, a user manages to lock themselves out because they enter the wrong password or username thrice in a row. I have changed the settings in the plugin so that when this happens, my client is notified at once. However, because he (for security reasons) does not have admin rights, he can’t unlock the user and needs to contact me to do it for him.

Which brings me to my question: is it possible to give users of a specified, non-admin role the capability to unlock blocked users? Such a feature would be very much appreciated.
