Plex Playlist question

Sorry if this is the wrong forum. I’m a bit confused with the new forum interface.

I just wondered if there is a way to make Plex (either web app or phone app) sort a watchlist by the run time of the items on it. I’ve been manually arranging them but this is tedious and I have to do it every time I add new items to the list.

1 - There isn’t a way to sort/rearrange items in a playlist.

2 - Run-time/Duration is not something that can be sorted.

Well, I was hopeful. I drag them into the order I want but couldn’t find any obvious way to have it rearrange them for me by time but just thought i’d ask in case I was overlooking it.

TY
