Hi @tkeyser5,
Thank you for participating in our community! At this time it's not possible to create a more top-level folder beside Plans and Project Files. This is an enhancement request and If you have any feedback that you would like to submit regarding any enhancement, please click on the “BIM 360 IdeaStation” link on the BIM 360 community home page. This will help the Project Manager and developers hear your voice on any changes/concerns with functionality directly for consideration in future builds.
Thank you and have a great day!
