Rest Apps API, allow key creation for existing extensions

When you make a new extension in FPBX, the restful apps will take and create the key for that extension, which is nice. We need a function that will create the keys for existing extensions. A prime example is I have a system with more than 300 extensions on it, and to start using your REST app's, it would take a year to add in the extensions one by one.

I would hope there was a way to make it go back and create keys for existing extensions..
