[Pan-users] Does 0.11.4 have a catch-up function?

[Beartooth]

I keep several groups on various servers subscribed that I rarely look
at, just because they're a pain to find ans subscribe/unsubscribe all the
time. Is there a way to clear out the old messages, either group by
group, or in a collection of groups, at one fell swoop? Or is that not
yet available in 0.11.4?
