Is there a way to change which V-Scanner folder is the power-up DEFAULT from the radio itself, without the PC? I will be making a trip without the PC and want to be able to change the default V-Scanner during the trip so I won't have to select a different V-Scanner everytime I turn the radio on. I know the default can be set using the PC software, but I want to change it in the field (as I could do with the PSR 500) which remembered the last V-Scanner loaded.
