Is it possible to see only new post replies? - sh.itjust.works

I’m new to Lemmy, days not weeks. Liking it so far and I’m trying to contribute in a positive way to the instance. I have one usability issue, trying to figure out which replies in a post are new since I last read it. I see the number like (4 New) telling me how many, but not which. Sorting by “New” hardly helps because of the threaded display. Threading is a good thing, IMO, since it preserves the flow of the conversation. But new replies to older replies get buried with a “New” sort. When the post has only a few replies total, I can keep up simply by re-scanning the whole thread. On more popular posts that becomes infeasible. Please don’t beat me up too bad if I’m missing an obvious thing! I saw the user settings, “Show Read Posts”, but that seems to be post level, not reply level.
