Rendering partials and assets in non-app folder

I’m working on an Ember app using Ember CLI where it will be modified for different clients. Most of these modifications would be things like the nav items or assets such as logos or certain images. I’m wondering what is the best practice to get these resources to render in the app? Is it even possible?

So for example, I would have a partial in a folder called client that is at the same level as the app folder. Could I render this partial in the app itself? I’m guessing things like static assets such as logos I could just stick it into the folder and add a line in the ember-cli-build.js to include it in the asset pipeline.
