You, as a Training Academy's administrator, can create bundles of courses, publish them on the Marketplace and sell them as bundles.
You can create a bundle by navigating to your Admin and then clicking Bundles in the side menu bar, then Add New Bandle.
To create a bundle, fill in the form with all the details needed. You can select the bundle's courses from your available list in the right-hand column. Simply click the course's plus symbol to add it to your bundle. To remove it click it's "x".
You can edit the bundle's Pricing Plans and select your pricing plan for this bundle. Choose between a License-based and a Subscription-based plan and add a Tier Pricing.
To confirm click "Save".
Then, on the Academy's "Bundles" page, you can make your bundle visible at the Marketplace, by sliding the toggle from "no" to "yes".
