Hi Aaron 

Thanks for posting in the community! I am happy to help here. Group Admins do not have the ability to modify group membership. A Group Admin can manage the following for the users assigned to their Group:

• View a list of users


• Manage licenses


• Delete users from the Enterprise account


• Transfer documents when delicensing or deleting a user


• Edit user details such as name and email address


• Export User list as a .csv file

To learn more about Lucid admin roles please see this help center article. In regards to your other question there are a few ways to add more than one person to a group at a time. To manage the group(s) of users that have already been added to your team: go to the admin panel > users tile > you can select multiple users by clicking "Command + Click" or "Shift + Click" > and then click "actions" and "edit groups."

If you are trying to add new users to your team and select their group: go to the admin panel > users tile > select "add users" > select "add multiple users" > you will then have the option to add multiple users to your team at a time and select their group (see first screenshot below).

You can also use a CSV upload to either bulk add users to your team (and assign their group) or bulk-update information for existing users. The information in the CSV file will overwrite existing users' current first names last names and groups. Please see the second screenshot. 

I hope this helps!
