[Elecraft] KRC2 Question

[Lew Phelps K6LMP]

I'm thinking of ordering a KCR2 Band Decoder from Aptos. 

I'm trying to figure out how it could be configured to control antenna selection based on mode of operation. My station has Yagi beams for UHF/VHF weak signal work, and also verticals for FM and repeater use. I know I can get the KCR2 set up to select the appropriate relay readout for a given band, but I can't see a way to automate the process of selecting between the two available antenna on (for example) 2 meters. 

Obviously I can do this with a manual switch setup. Any way to automate it so that I won't forget to change antennas when I switch from SSB to FM?

Thanks,
