Unfortunately, there isn't a property that can give you the current sub routine name
This means, as has been suggested, you're going to need to set the routine name somewhere. One thing I like to do, inside any "useful" sub routine I add: Note="nameGoesHere"  
This way if you are logging Notes, then you'll see the note in the log – which helps you know that routine was called, etc.
