If you want vector, why not have Splat output its L-R path-loss contour data into a text file and then do some scripting on that file to generate your contour of interest.  Make the cutoff some dB, plot only up to that dB of loss, then strip out all points nearest that dB in the contour file.  Use the points to generate the multi-line packet showing the region of maximum acceptable loss.
