Thanks for responding but I believe the solution you are suggesting will not work for me in this instance. As mentioned, I am planning to profile the groups so I will need a way to isolate/filter these respondents.
All you need to do is to switch the pills around and you can adjust the view to be able to profile either age or id. Unfortunately your data doesn't really show much more complexity than this so its hard to crystal ball what you are looking for. In the below screengrab I changed the mark to a circle, and exposed the age(group) field as a filter.
