Incorta customization to allow subtotal columns to be created by assigning a custom if-else determination for subtotal calculation columns. For example, if a column can be yes, no, maybe; we can evaluate the result:
if( result == 'Yes'): 1; else(result =="No" or result == "Maybe"): 0
This would allow subtotals to be easier to calculate after loading data. into Incorta.
