Can't resolve directory using Resource Root

I'm having trouble resolving directories in my import statements. I have the following file structure.
   

    Content Root/A/B/C/lib.js
    Content Root/Navigation.js

I have A/B/C/lib.js under the Content Root of my Module. If I add an import statement as
    import Nav from "/A/B/C/lib.js";
to the Navigation.js file located in the Content Root then the path resolves as expected. Because of various reasons I need the import statement to be
    import Nav from "B/C/lib.js";
but still have the lib.js file under the "A/B/C" directories in my Module.
    Content Root/A/B/C/lib.js
To solve this I was reading that I could mark the "A" directory as a Resource Root then I could reference the "lib.js" file as if Navigation.js was under "A" or "B" is now directly under the Content Root.
    import Nav from "B/C/lib.js";
Setting "A" as a Resource Root did not do what I expected as described above. I'm not sure it did anything because I still get "cannot resolved direct 'A'" errors. How can I resolve the path "B/C/lib.js" to a file located under "A/B/C/lib.js"?
