[Antennaware] Change Far Field Distance In EZNEC

Does anyone know how to change the distance from the source (R) at which far-field calculations are done in EZNEC? Yes, I know I can scale the results by scaling with e^(-jkR)/R, but it’s tedious to calculate each time I want to change R.
I have gone through the manual a few times now, and the only values are either one mile or one km. The NEC RP card lets you make the change, so I know that Roy must be setting the parameter (or maybe not).
Apparently, Roy isn’t answering questions on his website anymore.
Finally, I know I can export the 1 km numbers to Excel or MATLAB and do the calculations, but it’s much easier to do them in EZNEC. I guess I can just run NEC5 with cards, too, but again, it’s easy with EZNEC.
Thanks for reading,
73, Jeff
