I think this is a fantastic idea! I suspect that there is a way to distinguish these cases if someone dives a little deaper into the internals.

I'd never thought of this idea, but upon hearing it, it is such a good idea that I'd be a bit surprised if someone hasn't already tried this and perhaps succeeded (or figured out exactly why you can't do it).

Anyway, I'm very interested in seeing this tool become available. Please consider posting this as a new root node, especially if you don't get any useful responses in the next while.

Thanks much. I'm looking forward to being able to do:
