Greetings rgong1,
I can confirm it’s not currently possible to display group set names within EndNote for iPad. As mentioned earlier in this thread, we’d suggest adding the name of your group set to the beginning of the associated group names. For instance, if you had a group set called ‘Group Set A’ and that group set contained five groups, we’d suggest naming these groups “Group Set A Group 1”, “Group Set A Group 2”, “Group Set A Group 3”, “Group Set A Group 4”, “Group Set A Group 5”. I can definitely understand this solution isn’t ideal when working with as many groups as you’ve mentioned, and apologize for any inconvenience, but I’ll certainly add your vote to this product enhancement request.
