I am drawing a Bar Chart using this code:

outlabels={"Label1(1-10)", "Label1(11-20)", "Label1(21-30)"};chartouttable={{1, 1, 1}, {2, 3, 2}, {1, 1, 1}};BarChart3D[chartouttable, ChartLayout -> "Grid", 
 ChartLabels -> Placed[outlabels, Center]]

And I get:

1. The problem is that each label is on there three times. I know that I can put them on the Axis to only show them once but I want them on the side of the first series and vertical if possible and only once. Is there a way to do this?
2. Also, I would like to add labels to the series axis but can't figure how to. How can that be done?
