A year has passed since my previous comment, yet there’s no built-in replacement for OverrideNativeName.
However, I’ve got a solution if you’re still seeking custom cheat names like ‘Category.SetGodMode’. I’ve created a plugin just for that. It’s simple to use: download it, place it in your game’s Plugins folder, make your cheat manager inherit from the Meta Cheat Manager class, and finally use CheatName keyword instead of OverrideNativeName.
To download the plugin, or get more information, visit the GitHub page: GitHub - JanSeliv/MetaCheatManager: Plugin allows to call any cheat function in 'Your.Cheat.Name' format from the console in UE5.1
