'winged' button in segments for 'group+next/back'

Hey there. Segments and group+next/back is a cool tool for selecting. I would like to see a 'winged' button to increase its power even more.
Example:
-fixtures 1>10; segments 2
-when pressing group+next you get 1+2, 3+4, 5+6, 7+8 and 9+10
-when activating 'winged' you will get 1+10, 2+9, 3+8, 4+7, 5+6
So you can select symmetrical pretty quick.

While waiting for it we could still use a special group.
Like in the good old HOG2 days. As all this is selection based

But wouldn't it be handy to press one button?
"wings" as selections are pretty common. At least in my world :-)
An example:
Make a 10x10 grid of 100 desk channels.
Select the left half from left to right using area selection and the right half from right to left using the area selection.
Segments 5 Buddy 10
Group + Next
I'm just wondering how this is done on other console brands?
