It does not seem like it would have this indication by parameter (searched through the manual). If confirmed, this would be surprising because, with the screen, this is very easy to implement. It would be equally convenient to show the current pot’s value on screen, with a dot or star next to it whenever the position is equal to saved state. Maybe something for a future firmware …
At this moment, passthru pot mode looks like the closest you can get for guessing the actual preset pot positions. Not very precise though, for you have to set each pot by ear. For live performance, you’d probably also want to switch back to either relative or jump pot modes.
