So i have imported my Steam and GOG library into Launchbox a couple months ago. Now i have purchased some games from the Winter Sale from GOG and Steam. Is there a "update" feature that will go through and only import the new games? I have ended up buying duplicates at one point so doing an import of everything and just ignoring duplicates might not work as i do want both the Steam and Gog version in my Launchbox. Has ETA Prime or anyone done a video of this kind of situation? Thanks
