@Bangaio65,
No, I have several different hashes but I never made it that far since I was unable to make the script work. In all the excitement to add this script, I did not consider the possibility that the filtering would create incomplete part files for every torrent so I would have had to do exactly what I ended up doing which was to create an executable to handle three file extensions(two by name and one by extension) and set the client option to silently execute it immediately upon the completion of each torrent. So this prevents any post manual clean-up or accumulation of junk files. If the regex 'either' symbol requires v4+ then it would not have worked for me either since I'm on 3.6.

Hey, for those who still need it: I've made some updates to the script, including automatically fetching the torrent list and some other QoL improvements: https://gist.github.com/talanov/29bacef1ba1cb7aa89caa4c0bc9cb9bd
