Welcome to the community, @Carlee_Wooddell! :grinning_face_with_big_eyes: Your question is definitely in the correct category.
In situations like this, what I often do is create a formula field that creates the group sorting mechanism I want, and group by that formula field.
What are the other criteria that would affect how the group types are sorted? The more specifics you can share about your use case, the better we’ll be able to provide some formula examples that might work for you.
