Can the AET be used to create a new Z table?.

I understand that new user tables can be created/changed via EEWB, but, I keep reading that in CRM 7 we should now be using the AET tool. Can I create a new user table in AET, and if so, how?.

I only know of one way to launch the AET via the WebUI, and that's via the screen configuration tool. Of course this method would only allow us to ammend an existing structure/table and not create a new one, hence my question.

Anyone.
