When you put all individual units in a huge formation (archers in front, cav on the sides, ...), you can macro group them.
If you move that ordered group, your personally set-up formation disappeares en you can only form a chosen preset formation (default: line).
Is there a way to remember your set-up formation when moving? Like in TW.
If not: can it be patched?
(soldier < unit < group < whole army)
