Add additional project file at root level?

[aleph1]

I am wondering if it is possible to add additional projects at the root level when including other libraries in a project. For example, I am including Entt, and would like it to appear at the same root level as Kore in the project navigator in Xcode (see attached image). I tried a few approaches, including seeing whether an instance of the main project is being passed to the korefile.js at the project root, but I couldn't find it. This is the code I am using in the project's korefile.js:

let project = new Project('MyProject');

// add Entt
project.addFile('Entt/src/entt/**');
project.addIncludeDir('Entt/src/entt');

// add sources
project.addFile('Sources/**');
project.setDebugDir('Deployment');

resolve(project);
