Option to change modulation/frequency when sending saved files

Another cool thing to have would be the option to change the frequency/modulation when opening a saved .sub for sending… Meaning if i open a .sub saved on 868.35 FM have the option to send on 433.92 AM for example without the need of editing the saved file. Both on READ and READ RAW format … It would be very handy. For example one would open the file as usualy and would have an option to change the frequency/modulation even if one would still have to chose from the ones written on setting file…
