Thanks for the feedback.Even in the in the current release it is possible to setup more than one scene in a project. This is done by setting up your scene elements in different areas of the work space and then use the camera switch controls to move between scenes.
However the work involved really outweighs the benefits as it is simply much easier and quicker to build separate projects for each scene and then edit them together afterwards.
This is unlikely to change in CTA2 I'm afraid.
