Quacks - iPlayer release before broadcast

[RS]

Is there any support in get_iplayer for programmes like Quacks, p0596d3l, 
where all the episodes are released at once but they are only broadcast once 
a week?  There was something similar on Radio 4 a few months ago with daily 
episodes.

The wiki has
https://github.com/get-iplayer/get_iplayer/wiki/documentation#searching-the-future-programme-schedule
but I don't think that does what I want.

So far it hasn't happened often, so it is no hardship to download by PID or 
wait for the broadcast, and it isn't worth any effort to support it, but I 
was just curious whether there was something I'd missed.
