Autoloading nested files?

Question

In my Laravel package I have some of my model traits under /src/Models/Traits.

The src folder is autoloaded in composer.json:

"autoload": {
        "psr-4": {
            "Acme\\Package\\": "src"
            ......

Therefore any file under src can be used in the packages parent application by:

use Acme\Package\SomeHelper;

Is there a way to keep my traits under /src/Models/Traits but have them accessible in parent applications like:

use Acme\Package\SomeTrait;
