How can I control the manage lists button?

The manage lists button appears on the subscriber membership component.  However, if you are using our limited permission set this button will not appear, by design.  If you would like to keep the user on the limited permission set but provide them with the button you can assign the custom permission - wbsendit.Manage Memberships

There are two options for the assignment:

1. Go to a profile and select custom permissions and add wbsendit.Manage Memberships
2. Alternatively, you can create a new permission set and select custom permissions and add wbsendit.Manage Memberships
