How to Change Watchlist Sort Order back to Original Order setting

After sorting by title, country, year or any of the other headings in the default Watchlists, is there a way to change the order back to the original settings (where the dramas or movies are listed by when they were added to list by me)? Please this would be very helpful for me, thank you!

So is this not possible then? I’ll just go ahead and contact support directly.
