Not necessarily easy, but definitely better. Also, a better contest 
logger might help. Here's an excerpt for your rig from doc for N1MM Plus.

I don't know if he's still around, but there used to be a guy (maybe 
more than one) building CI-V interfaces from an old QST article and 
selling them on the internet or at hamfests. They worked fine. Google 
found these on the first page

Over the winter, I bought cables to program a Kenwood TH-F6A and Kenwood 
TM-D71A (think that's the model number) on EBay from a ham in San Jose. 
They are reasonably well built and work fine. Here's his listing for a 
CI-V cable.

      7.20. IC-751/751A using address 1C hex

          + There are several limitations caused by the lack of some
            CI-V commands. VFO select and split commands are not
            supported. This will prevent the program from controlling
            the radio split and reading or programming VFOB frequency.
            SO2V mode should not be attempted and VFOB's Bandmap and
            Entry windows can be closed.

To communicate with the radio, the baud rate, CI-V Transceive, and 
number of bytes of frequency data must be set correctly. This is set via 
a DIP switch on the Icom UX-14 interface board. Using the DIP switch S1 
location in the beginning of the manual (page 11 has the DIP switch 
positions reversed) set S1 to the following:
1-------------6
On - Off - Off - Off - Off - On
This will set the baud rate to 9600, the length of the frequency 
information to 5 bytes, and turn CI-V Transceive OFF.
If the radio contains the Piexx UX-14 CI-V board, set the DIP switches 
per the Piexx manual for the same configuration
