GuessLensShift and 3 point perspective

I wonder if there is a way (perhaps a script?) to coordinate Rhino 3 point perspective with vray’s GuessLensShift lens manipulation.
Often times I forget to apply the latter in vray’s physical camera via the command visGuessLensShift (which is included in vray’s utilities) in a viewport with 3 point perspective specially whith wide angle views (small lens length).
Unless you do that, vray rendering will look different than the viewport. It is not fun to finish a rendering realizing that you forgot to turn on GuessLensShift and the nice vertical edges in the viewport are rendered with distortion.
Perhaps someone out there with scripting skills could write a routine to accomplish that? It would be greatly appreciated !
