multiple criteria for index sort (thread+recv)?

[Baron Fujimoto]

Is it possible to apply multiple sort criteria at the message index? For
example, I generally want my messages threaded (Sort Thread)
but I would also secondarily like it sorted by Received (Sort Recv)
option) so that more recent responses in the thread pop the thread to the
most recent end of the message index. As it is now, long lived threads
tend to migrate backwards because they are anchored by the oldest retained
message in the thread. Or is there some other way to achieve this?
