Add option to keep modalities together

[sarthakpati]

Is your feature request related to a problem? Please describe.
Currently, multiple modalities are displayed as the following:

Coronal_${Modality},         Sagittal_${Modality},         Axial_${Modality}
Coronal_${Modality}_${Mask}, Sagittal_${Modality}_${Mask}, Axial_${Modality}_${Mask}

which is good but it doesn't work well for manuscripts.

Describe the solution you'd like
For manuscript publication, it would be better to have the option to showcase the figure in the following manner:

# first rows contain all images but with each view coming at the same time
Coronal_${Modality_0},         Coronal_${Modality_1},         Sagittal_${Modality_0},         Sagittal_${Modality_1},         Axial_${Modality_0},         Axial_${Modality_1} 
Coronal_${Modality_2},         Coronal_${Modality_3},         Sagittal_${Modality_2},         Sagittal_${Modality_3},         Axial_${Modality_2},         Axial_${Modality_3}

# next rows contain the same view but with mask(s)
Coronal_${Modality_0}_${Mask}, Coronal_${Modality_1}_${Mask}, Sagittal_${Modality_0}_${Mask}, Sagittal_${Modality_1}_${Mask}, Axial_${Modality_0}_${Mask}, Axial_${Modality_1}_${Mask} 
Coronal_${Modality_2}_${Mask}, Coronal_${Modality_3}_${Mask}, Sagittal_${Modality_2}_${Mask}, Sagittal_${Modality_3}_${Mask}, Axial_${Modality_2}_${Mask}, Axial_${Modality_3}_${Mask}
