This tip is merely alleged because while I took a gasp of delight at discovering it for myself, who knows - it might have been obvious to others.
In recently stting-up a series of precise camera views of a tall object in a scene, upon testing the views, many of the lower cameras were too close.
I used the Resize tool to uniformly increase the camera distances.
Attached are some images showing the procedure.
In case you think I should have used a VR object to do this - I needed more angular precision so I placed cameras instead - it was for a slide show, anyways.
