Mass recheck all torrents to upload? Upgrading to new Deluge installation

[jang430]

Hi. Something is wrong with my Deluge docker container. I want to reinstall. Is there a way to start seeding files already on my NAS without force rechecking 1 torrent file after another?

I have tried adding 2 torrents that have already been downloaded into my NAS. I ticked on pause when added. I pointed it to the folder where the files are. After adding, force rechecking won't be able to show file as 100% downloaded, and start seeding. It will start downloading the file once again. Whereas if I do the process torrent per torrent, it shows 100% downloaded after force rechecking, and all I need to do is start it so it starts seeding. Any idea how to do this en mass?
