I have a game event sheet located under Event sheets > Game > GameEvent.
I also have a player keyboard event sheet located under Event sheets > Player > Input > KeyboardInput.
Within the game event sheet I have a group called Player which in turn contains a sub-group called Input, e.g GameEvent > Player > Input.
When I try to insert the KeyboardInput event sheet under the Player > Input sub-group, it remains at the top-most level at the beginning of the event sheet.
Is possible to insert an event sheet within a group or sub-group, and if so then what am I doing wrong?
