You can specify the angle of each face on the images tab without control points. Use the camera and lens tab to make sure the field of view of your images is exactly 90 degrees, and all distortion parameters are 0. If you get any small holes along the seams try making the images 91 degrees instead so there is a very small overlap. Once you've set this up once you can use the "Apply template" option on the file menu to copy the image angles and lens parameters from one project into another. I imagine there is a way you can do this on the command line, though I can't provide you with a script. I've noticed Blender's specular reflections don't line up between the images in its own cube map renderer, so you will likely have visible seems if you use specular reflections, whichever method you use to stitch them.
