Mass remove downloads

[sonikun]

I had added over 150+ games.. Unfortunately my hdd died so I want to remove all the "downloaded" ticks from all games but keep the "played" ticks and notes, ratings as it is. Am I missing any option to do this?

I would just filter by installed, and keep spam clicking the top most one because it will disappear once installed is unticked
