Amber,
Quick Base has a "group's records" capabilities that would allow users to only see records that members of their group added to that table. If that's something that would achieve your goal,
this help article outlines that process.
If that doesn't solve your need, my other guess is that you'd have to actually create a Groups table that contains a List - User field on it. Within that field, you would select all users that are part of that group, and add the List - User field to any relationships. This would then display that collection of users as a group is selected on any subsequent child tables, and your role settings can be set to "When the user is included in the LIST USER field".
