A work-around is to add extra cubes/faces (one for front & one for side profiles) to the Assembly room and then map your image to theses cubes. Place them at right angels to form a corner. Then position your model to be centered on these cubes. In the model room, display your Scene Preview window in 2 or 4 views mode & use the texture-shaded preview to display your images. Not quite as elegant as Infin-D but you do see real-time changes to your model in varied projections.
