How do I stop qbittorent from redownloading finished, but removed torrents?

When I finish 100% torrent, and then watch the video/install the game, I move the file to my external HDD. utorrent had the stop function which basically locked the torrent to forever stay at "100% finished". However, qbittorent (on every startup) checks if the files are still there (even if paused; and there's no stop button). This causes them to go to 0% and they want to download again (though at least they're still paused). This causes multiple problems.

One of the suggested solutions was deleting the files and then on next startup when they reset to 0% just uncheck all files so 0% is completed torrent (note: trying to uncheck them before removing files and restarting will automatically just check them back). This works relativity well with multiple-files torrents, though it creates subfolder (and .unwanted folder) again, so that's a bit annoying (and they still show 0%, not 100%). 
But when you do same with single-file torrent (with no subfolder), it bugs out and this happens https://i.imgur.com/MA5EsHy.png. It changes the torrent to be in a subfolder, it isn't reversible and the subfolder is sometimes causes problems because it has exactly same name as the file, including the extension.

Is there any way to **A)** mark torrents as finished and keep them that way (same as utorrent's "stop") **B)** Solve the problem with single-file torrents if I use the suggestion I've written about (and perhaps even stop the annoying folders from reappearing when I do it) **C)** At least, if nothing else, force single-file torrents to have subfolders by default, so they would behave like multi-file torrents (checking "create subfolder" when adding torrent does nothing) **D)** Solve it any other way

Serious question: why don't you simply remove the torrent from the list?

I too have wished that qBittorrent would not check the downloaded files on start/restart.

For me... I use the torrent list to prevent duplicate torrent downloads and/or to review the torrents details. i.e. TV show season #, episode #.
I can't speak for stramner, but perhaps stramner does too??
