Of course. It's a fairly simple system once you get used to it. But you might be better off asking Giorno. I'm not actually sure how much he's restructured since he took over.

[Bruno has never really bothered to ask since, well, you know. He doesn't exactly fit into it beyond acting as consigliere here in Ruby City. But there's still likely a distinct difference between how Diavolo chose to run things and how Giorno chooses to run them now.]
