Check
this out - not as direct as what you're describing but not as indirect as distinct callbacks for each calling screen. hope it helps!

Optional roSGNodeEvent Callback Function ArgumentNote that field observer callback functions can specify an roSGNodeEvent argument. For example, the changetext() callback function signature in the example above could have been written as sub changetext(event as roSGNodeEvent). In this case, the callback function can call the roSGNodeEvent functions to extract information about the node that triggered the callback, specific field that triggered the callback, etc.
