Is it possible to list only in-umbrella dependencies with mix deps.tree or similar?

I’m trying to generate a .dot dependency diagram of all the umbrella applications that I have. But looking through mix help deps.tree I don’t see a way to accomplish that.

Although one workaround would be to generate a list of all dependencies, then manually remove the folders listed in apps, and then pass that as a list to deps.tree. I’d prefer an easier way if possible! Maybe even just a --include-deps flag that I could pass to deps.tree that would only include those dependencies/applications.
