I know at first glance this seems ridiculous since the download paths don't exist until the files are downloaded, but my request is very practical and needed now that almost all posts have obfuscated File Names.
Here's my situation. I select a list of videos to download from my NZB provider. This list sometimes includes 1080p and 2160p versions of the same video. I'd like to put the 2160p videos in the Wish List and only download them if there is no 1080p version or it fails to download. The file names are obfuscated and gibberish, so seaching on them for 2160p doesn't work, but the NZB's are named with the correct file name of the video. So if Newsbin could also search on the Download Path, it would allow me to select all the 2160p videos and move them to the Wish List without having to manually do it one by one.
