help for v5s

i am trying to help a mate with a openbox v5s hd box
he got the box with the firmware and chn list installed
and there is no problem other than he wants to set the chns
in his own personnel order but you can from what i see only move
one chn at a time and with only one sat it needs a better way
after scanning and sort his own list, i have tried a few editors but
all say invalid file with the uploaded chn list from the box,
is there a chn editor or other firmware to be able to move the
chns like the tm/Dr boxes for example,many thanks for help and advice,

I have the same box and you can move as many channels as you like just highlight what you want to move, click on arrows (move) on the right and your away
