AddAction submenus

[Bangomango 10]

Is it possible to add submenus of actions with addAction? Like have an action "Make" that opens up to just the actions associated with it. Similar to this: Action menu -> "Make" action-> opens up submenu containing the actions "Satchel Charge" and "RGO Grenade".

Doable with removeaction and addaction. Obviously they are just action and doesn't include any graphic indication that they are "sub actions".
