Lukas, you should have explained your wish for those forum users, who have never worked in AutoCAD and do not have an idea what you are wishing!
So, I will try to do it:
In AutoCAD Arrow Tool Selection Methods are activated automatically by the direction of movement of the mouse - Entire Elements Selection Mode is activated by moving mouse from left to right, and the Partial Elements Selection Mode by moving it from right to left. As easy as that!
Compared to this way of selection the AC way is horrible!
