Hey
@staynavytom, thanks for posting your question to our Community.
At the moment, inviting
groups of people to a folder, instead of individually, is a feature available only for Dropbox Business members.
For personal (Basic, Plus, Professional) accounts, you can invite users individually.
You're welcome to post an idea about this, though, on our
idea board for other users to up-vote.
Let me know if you have any questions.
