Organize Models in subdirectories

Hi, we are using subdirectories in our projects no separete views and controllers but in models we didn’t learn yet. Recently I’ve found this https://github.com/cakephp/cakephp/issues/6045 and actually routes and plugins we are already using, we just want to separete our models like this:
Model
-Entity
–Financial
—Money.php
-Table
–Financial
—MoneyTable.php
I’ve tryed put like this then controller is not able to find his model. How can I do to organize it, and make it work?
