I believe I have seen that option, but I don't have any buttons on the shifters assigned to any of the Garmin Channels. When configuring the shifters I only have the option of assigning front and rear derailleur up and down shifts. I'm pretty confident that changing it the DFly unit to the newer version will make this option available.
