Skybox F5S how to sort favorites?

[cenuro]

Hi,
I created my favorites using AliEditor from the skybox.cc website. I use the Skybox in a holiday apartment and each language is a favorite and contains the fitting channels.
Unfortunately AliEditor doesn't offer alphabetical sorting inside a favorite.
Or lets better say: the sorting with - and + isn't really usefull if you have lots of channels inside a favorite.

But I neither found this option in the Skybox. I can't believe such a basic function is missing and I guess I just don't now how to do it.
I am using official firmware from 4/2014
Please help, thanks!

Menu ->Edit Channel ->TV Channel List, select the desired satellite, press the blue button(Edit), and then the red button(Sort), the name(AZ it) and press SAVE to save all the channels in alphabetical order.

Unfortunately I do not have this option.

Menu -> Edit Channel has 3 items:
Channel Edit
Favourites Edit
Delete All
but no TV-Channel List

None of the 3 menus offers me a blue button
