Same here. It would be nice to not only set the size of the rendering but also the origin, or center. This would help crop a lot context out, especially in architecture.
The image is from TM. I can tilt the camera and then fix it in a pixel warrior software, but there will be barrel distortions.
It would be cropping the upper right hand of the composition. That is what you can do with an optical tilt lens. Easy to do in several other software.
Hope here is a solution and I have missed it in the docs.
