This is a long-standing frustration of mine: in OmniFocus, "subprojects" (in quotes because there is no such thing) don't have project status or characteristics. As you note, Action Groups cannot be selected when filing an action via Quick Entry, thus requiring additional steps before you can get the action to the right spot.

Seems like a no-brainer to me, although I'm sure there are valid viewpoints to the contrary.
