I have many groupings stacked on each other. There is the option of hitting the arrows left or right to cycle through them. You can also hit the button to bring down a drop list. There is only room for about 10 on the drop list and would expect a scroll on the right to select more then those 10 but there is no such scroll. Is this a missing feature? I have about 30 groupings stacked and cannot select via dropdown or reorganize beyond the top 10. Any suggestions?
