Hello,

I want to enable check() in shipping builds. The current way to do this is by modifying project’s Target.cs file like

```auto
//Project.Target.cs
if (Configuration == UnrealTargetConfiguration.Shipping)
{
    BuildEnvironment = TargetBuildEnvironment.Unique;
    bUseChecksInShipping = true;
}

```

The above method requires us to have source code of unreal engine for build, because of the `BuildEnvironment=TargetBuildEnvironment.Unique` setting. But, I do not want to do it this way, because having source code to build project as a requirement is bad for my project. Is there another way to use check() in shipping builds?

Cheers!
