Mag boxes get the channel list by the folder categories that your IPTV provider assigned; but you can change the order the way you like and put your desired channels right beside.
Update: Since February 6, 2021 we dont support Stalker portal anymore.
This post is just informatory.
 
To do that you simply need to:

1-Stay on the channel you want to move
2-Press the blue button, then the channel becomes movable
3-Move the channel to where in the list you like using up/down buttons
4-Finally press the OK button to confirm the order
