in Kmail, is there a way to arrange email threads by subject & date only, and without sub-threading mesages?

i'm specifically after this type of view for mailing lists, where it works similar to google mail.

the most recent update in a thread, puts the thread to the top of the view, but once you open each thread, the view is flat and arranged purely by date/time rather than who replied to who (which find awkward to follow threads)

searches aren’t being very helpful, but i think that might be down to not knowing the exact term im after.

is this type of view possible?
