Can we pass multiple subtotalN parameter for grouping data in template itself?

Hi Team,
I am trying to use smart marker with grouping data in excel template.
In my use case, I am using multilevel grouping and I need to perform summary function upon one column field with respect to the multiple group column. For example - On a column I need sum for amount with all the group column.
I was able to achieve subtotal for one group with this smart marker and formula &=rows.cell7(subtotal9:rows.groupCell1, numeric).
Is that possible if for the same column we can pass multiple subtotal parameter. For ex - &=rows.cell7(subtotal9:rows.groupCell1, subtotal9:rows.groupCell2, numeric).

I am attaching the template and desired output file.
PFA for the same.

Thanks
