Are There Any Page Size Settings For Agilian 11?

Hello all.
I am using Agilian 11 and am not able to find any options to select a page size for diagramming. I am looking for a feature that would allow me to set my document size according to well known output size formats such as Legal, Executive, and A4. IS Agilian 11 capable of letting me set my drawing area to any sizes? I don’t see any options for this.
