Quit Upon Particular Download Completion

[SaintDogbert]

I noticed that 1.7 BETA contains a (seemingly) new feature to quit upon downloads completion, but because I often have very large torrents running in the background but only really care about a small one or two that I need immediately (to conserve bandwidth use) it would be really helpful if in individual torrent properties there was an option to quit utorrent after its download completes. The only other way I can think of doing this would be having it execute upon completion taskkill.exe but I don't think that would be a particularly great way of doing it

Thanks!
