Creating a data import page for Laravel Voyager

I am using Voyager for a basic BREAD admin to a small web application I am building for a small non-profit. Yearly they need to import 300-500 new semi-complex entries into the database from Excel, so I want to build an admin script that will store all the data in the right places automatically.

Is there a structured way to add a custom controller/view to Voyager?

(I have not found such documentation yet, maybe I am blind. So I have started manually extending existing bits of Voyager, but as I get deeper I want to make sure this is the best option for future growth.)

Thank you.
