The vast majority of Baofeng/Btech radios do not have field programmable (upgradeable) firmware, so I suspect the answer is 'never, unless we go in and update the firmware to accommodate this and build more of this radio with the new firmware, but your current radio will never do this'.

Does Baofeng/Btech offer their own CPS that offers this ability? I suspect it does not.
