Hi there, 2 issues

If i want to setup RSS downloader in utorrent in order to seed the same show on multiple trackers how would it work?
Usually the name of the show is published with the same Dir name in private trackers. so basically instead of wasting hard drive space rss downloader should rehash/cache to the same directory
The Q is if the program doing it by-itself (rehashing without question)

2. How can i prevent/filter Tvshow that i want to download from X site and not from Y, even if Y site listed in my custom feedlist.
