This script is dependent on the get_iplayer application being installed and it's Web PVR Manager module being active, (https://github.com/get-iplayer/get_iplayer/wiki/installation
For every show on BBC's iPlayer site the script injects 2 pink buttons - the one on the left adds that show's URL to the Quick URL queue (you can then just close that new tab), the one on the right performs a get_iplayer name search (you can click to record series etc as normal). In both cases, the show's category( History, Drama, etc) and it's name can be appended to the recording directory.
Once you're done choosing your shows just start the 'Run PVR' from the get_iplayer Web PVR page.
I wrote this on Windows 10 / Chrome / Tampermonkey and haven't tested it widely on other setups, so there may be issues, which I will try and address. Also, this is my very first Greasemonkey script so I may not have done everything in the most efficient manner.
There are a few quirks. One is that the BBC page lays out, then performs some other loads, and only then does the script fire, so you may need to wait a few seconds for the pink boxes to appear.
