When I start a fresh installed IRIS or a Container I always find Interoperabiliy (aka. Ensemble) mapped to namespace USER.

Is there any utility to remove this mapping by a click ?
unmapping it global by global, routine by routine,  Package by Package is just a boring exercise.

To be clear: I look for a utility inside IRIS.

The external utility is obvious: Notepad (or any other text editor) 
- clean iris,cpf,
- restart IRIS
It's fast, it's efficient, but it's really hardcore.
