Would it be possible to upgrade the firmware on the Makro Multi Kruzer so that it would be possible to save different frequencies to the different modes? At the moment, if one of the frequencies is saved in one mode it carries over to all of the modes. I think that it would be very helpful to be able to save different frequencies in different modes for example 14kHz in 3 Tone and 19kHz in 4 Tone and be able to switch back and forth without having to go to Options and switch the frequency. Thank you.
