QObject::isSignalConnected() is a fast way to tell if a slot is connected to a signal. Is there a simple way to check if a specific signal on a QML item has a connection?

My Item changes its appearance to indicate that it has a connection on the signal, but I am doing that with a bool property. I would like to get rid of the property and just rely on a test like "isSignalConnected(mySignal)".
