Feature request: update job's torrent file

[JohnTheCoolingFan]

I often have to "update" a job in order to get new files (new episodes, fixes, etc). My usual workflow is to delete the job without removing the files and add a new job with the new torrent file. That resets the job settings I may have set and the label. And I always have to go and put all those settings back in.

It would be awesome if I could just update a job's file through UI. It could be as basic as just automating the things above or even take advantage of comparing the contents of the new torrent file to the previous one and possibly skip checking data of some files.
