That one would be juicy BUT it could fly against the spirit of Playmaker's FSM interface.
Also, if such a function were to be implemented, I think whatever aspect the collapsed group would adopt, it would need to offer a summary of the basic data present inside: number of states, number of events and transitions used.
The group itself would work like a big meta-state, with its own entry and exit transitions.
I would not call this function an urgency at all though.
