You are able to re-arrange your Group Sets easily.
1) Simply click & hold your mouse on the Group Set you want to move.
2) Drag and drop it "in-between" other Groups Sets. Drop it when you see two horizontal black lines (it is a tiny space).
At first, it did not work for me because I was not dropping it at the right spot (re: where the black lines are).
Hope it helps,
