Highly highly agree! :-)
And to add to this, it would be nice if it could be caller ID for regular outbound calls OR e911. Some of our customers want their different locations to show different outbound caller IDs, and remembering to set it on the device level (along with e911 caller ID) is a pain!
So I guess basically just adding the standard caller ID options, but also for a group and not just for the account, user, or device.
