This feature is specifically for .cjson files.
JSON files or CJSON files can be imported, any number of times in any location of the cjson file.

file1.json:

{
    "hello": "world",
    "name": "Shan"
}

file2.cjson:

{
    "file1": $import "./file1.json",
    "gender": "Male",
    "age": 21
}

Target Json Object:

{
    "file1": {
        "hello": "world",
        "name": "Shan"
    },
    "gender": "Male",
