For anyone else who runs into this problem, I finally found a video explaining how you can do this w/o starting a new project. Regardless of what your project is/what options you selected creating it, if you want to include any of the start content templates simply click “add” in the content browser-> “add feature or content pack” → then select the template you are needing assets too. This doesn’t change any of your current project settings and simply gives you the starter content for the template you choose and adds it to your content browser.
