You can prepare your data such that two grouped column plots are made on top of each other with two layers.
1. preapre data, assume x y1 y2 y3 as follows (3 member group)
A B C D E F G
x y1 0 y3 0 y2 0
2. Ploat ABCD as column plot
3. Add right Y layer
4. add EFG into 2nd layer, and group them
5. change EFG into column plot and then just setup the plotting details to be what is expected in the empty column in layer 1.
