Request Alias Hot Key .

I'm not sure exactly what you are asking for, but if it is a way to quickly enter a Control Alias for a given control or a group of controls, select the control or controls and press Ctrl+Shift+x. This will bring up the Expression Label window wherein you can specify either the Control Alias for your control or a string to automatically enter the Control Aliases for all of the selected controls.
So, it is already in there.
Ctrl+Shift+x = Expression Label for Control Alias
