SteamGridDbManager

Sure you can do that on Steam either as adding any game as non-Steam game from menu or use tools like this to do that.

You should really use steamgriddb manager to set consistent images that's what ROMs ce done and it looks great https://www.steamgriddb.com/manager

Steam already has that feature way way before even others were a thing back then. It's https://help.steampowered.com/en/faqs/view/4B8B-9697-2338-40EC and to do this in a shortcut, you can use https://www.steamgriddb.com/manager to import your "installed" games from other launchers.

Steamgriddb manager? just googled it, https://www.steamgriddb.com/manager found that it is not under development? I didn't plan to replace it, but I can imagine that there is probably some overlap.

Have you tried SteamGrid DB Manager ? It has worked to import games for Epic and other launchers before. I have Battlefront II from Epic sure also and i think I used that to import it.

for Epic and the rest: I would use https://www.steamgriddb.com/manager (or https://github.com/WombatFromHell/OriginSteamOverlayLauncher) for this sort of stuff...but it may be reliable for certain games (aka Call of Duty Warzone).

There is also this manager which is made for many launchers to be easy to import into steam. I've never used it personally and don't know if it's made for steam input in mind.

Will take the chance for a shameless plug: If you're a Linux Steam user (or plan to be sometime in the future), and want a straightforward way to manage your libraries (or backup them, or even have them shared in an NTFS drive), feel free to try my steamlibmanager script. Hope Gitlab counts :)

The good news is that I automated this procedure long ago, here you can get my script. Simply pass your NTFS library folder as a parameter (although, I really recommend not to use your main Steam Windows library, but a secondary one).
