Assigning content to a bundle is the final step if you are creating a new bundle, or can be a future step if you've already created one and want to assign new content.
To assign content to an existing bundle:
Navigate to Bundles and click Edit next to the bundle you want to adjust
Click on STEP 2 (Assign Content)
On the search bar, select the content you want to add
Click on Finish when you don't want to add more content
If you want to add all your content to a bundle, instead of searching for it, you can click on Assign All. However, if you want to remove all the content selected for that bundle, click the In Bundle tab and click Remove All. This will save you time from having to assign or remove every video you have in the bundle.
