How to configure code inspector dependency path

We're using Defender's Code Inspector on our github repo. It is working great, but because of the nature of our contract, the dependencies live in a subfolder in the same repo. Defender sees all the code as contracts and nothing shows up in dependencies.

I've searched the docs and github and it seems that defender.config.json would be the place to configure the dependencies path, but I haven't found any such config.

How can I tell Code Inspector which folder contains core contracts and which is dependencies?
