In WD ALV subtotal, display field summary which have same data in subtotal line

As seen is screenshot below. My requirement is to show summary of fields which are not sorted or total having same data in my subtotal line.

Eg. In this case for material number I have done subtotal.

Material number is displayed in line of subtotal. But material description is same for the material highlighted below.

I have to display both material and material description in subtotal line.

Also, I cant change the field on which I have applied sort.
