Yes you can! This is referred to as creating subgroups, which you give unique names and then add team members to. To create subgroups, click MEMBERS (1) on your campaign home page and then "Create subgroup" (2). 

Enter each name of the subgroups one at a time.

Example of subgroups with no team members:

The list of team members that are not assigned to subgroups is located at the bottom of the 'Members' page.  Either the individual can choose their subgroup, or the coordinator can assign the subgroup. To do this, click on the 3 red dots.
