Visualize batches of 3D Volume along rows and slices of each volume along columns

[msrepo]

I have a batch of expected and target 3D volumes. How do i visualize each volume along a single row as slices and different volumes along different rows.

This visualizes each batch as rows with slice no 32 to 96 of each volume. This visualizes everything into one single row though.

RowVisualizer: # stack the outputs of child visualizers as rows of an image grid

      RowVisualizer: 
        input_mapping:
          global: [B:  '0:8', D: '32:96:8' ]
        visualizers:

          - DifferenceVisualizer:
              input_mapping:
                prediction: 'predicted'
                target: 'target'
              cmap: viridis

Doing this does not help:

ColumnVisualizer:
  input_mapping:
    global: [B: '0:8']
      visualizers:
            - RowVisualizer: # stack the outputs of child visualizers as rows of an image grid
                input_mapping:
                  global: [D: '32:96:8' ]
                
                visualizers:
                  - DifferenceVisualizer:
                      input_mapping:
                        prediction: 'predicted'
                        target: 'target'
                      cmap: viridis
