I keep a specific profile that sets the enterprise cui as the main cui. That way I can bounce back and forth without really thinking about it.
The LISP routine I linked above precludes the need for that, making it possible to change Enterprise CUI to Main CUI in your current session, allowing you to make changes to Enterprise CUI (as Main), and when done, restores original CUI settings Enterprise == Enterprise, Main == Main, etc.
Cheers
