See any bookmark option available

See whether there is any bookmark option available. A course with a number of video to watch. Very often, I will not finish it all the same day. When I go back the next day, it is a bit hard to search what I left off yesterday. If there is a kind of “bookmark” / “last read course” would be great appreciated. Perhaps, there is a good way to do it which I do not know yet. Thank you.
